Managed Server, not just Hosting but also Linux consulting, DBMS and security.

When you first visit our site, it's natural to be impressed by our high-performance hosting offerings, designed for CMSs like WordPress, Joomla, Magento, and PrestaShop. The homepage and main content rightly highlight the advantages of speed, stability, and optimization. However, limiting yourself to this first impression misses the essence of our work.

Managed Server SRL is much more than a hosting provider: we are first of all a technical partner specialized in systems consultancy on Linux, open source DBMS, cybersecurity, and mission-critical infrastructure. Unlike many other players in the industry, We are not tied to any particular datacenter e We have no proprietary infrastructure to push or sell. This approach vendor independent, free from conflicts of interest, allows us to assist the customer impartially, suggesting solutions and suppliers based on actual technical, budget and scalability needs.

In this article, we want to share what's really behind our services: a technical team that works every day on complex Linux environments, supporting agencies, developers, and companies, and that focuses on the quality of the infrastructure, not the sale of resources.

Not just hosting: infrastructures designed, built and maintained with care

Hosting is the starting point. The showcase. What you often see first. But for us, it's just... the tip of the iceberg of a much larger systemic work, which covers the design, configuration, security and ongoing maintenance of the entire application stack.

Behind every hosting plan we offer are dozens of carefully crafted optimizations, monitoring tools, security policies, backup routines, and automations. And this approach isn't limited to our infrastructure: we also make it available to customers who have Dedicated Servers, VPS or cloud environments, public or private, to be optimized or made safe.

In many cases, we come into contact with realities in which the infrastructure has grown in a haphazard manner, perhaps by adding disparate components over the years, improvised configurations, or choices driven more by urgency than by a coherent technical vision. In these scenarios, we intervene not only to solve the most obvious problems, but also to bring order, method, and sustainability over time.

We analyze application dependencies, document what is missing, eliminate architectural bottlenecks, and, most importantly, work side by side with internal stakeholders to transform fragile infrastructures into robust and scalable environments.

Our goal is not simply to “make things work,” but to make them work well, with room for growth, operational visibility, and a systemic management that minimizes breaking points.

Furthermore, we interface with third-party suppliers, software houses and development teams, acting as a link between the application and infrastructure components. This allows us to contribute concretely to the testing, release, or refactoring phases of hosted applications, maintaining high technical consistency between the developed product and the environment in which it will be deployed.

Finally, let us also pay attention to the management and operational aspectsWe document procedures, standardize configurations, track changes, and create environments where even staff turnover or handovers can occur seamlessly. This rigorous yet flexible approach is an integral part of our consulting approach: We do not provide packaged services, but tailor-made solutions, built to last over time..

Advanced Web Server Consulting: Apache, NGINX, and LiteSpeed

We know well that The web server is the beating heart of any web architecture, responsible for providing resources, managing connections, and communicating with backend services. For this reason, we offer Advanced technical consulting on Apache HTTPD, NGINX, and LiteSpeed, the three most consolidated and reliable technologies in production contexts.

Su Apache, we intervene on both legacy installations and updated environments, modulating the parameters based on the expected load and the type of applicationWe manage MPM configurations in detail (especially Event and Worker), optimize the management of KeepAlive connections, work on the directives mod_deflate, mod_expires, mod_headers e mod_security to ensure a fast but also secure response. We also provide support for installations where .htaccess is used extensively, offering suggestions for moving configurations in VirtualHost and reduce parsing overhead. This approach is particularly useful in shared environments or with dozens of virtual hosts managed by a single Apache process.

With Nginx, which we increasingly use as a reverse proxy or main web server, we deal with low-level configurations, taking full advantage of its asynchronous design and ability to handle thousands of concurrent connections. We optimize buffers, configure static resource caching, rate limiting, HTTP header checking, and Brotli compression. We support application development by creating optimized location blocks, managing conditional redirects, and using complex maps, variables, and rewrites. In more advanced contexts, we configure NGINX as an L7 load balancer, integrating it with PHP-FPM, Node.js, or WSGI (Python) backends, with full support for SSL/TLS, HTTP/2, and HTTP/3 (QUIC).

LiteSpeedFinally, it's an excellent choice for those seeking high performance with simplified management. Its event-driven, Apache-compatible architecture allows for excellent results with WordPress and WooCommerce, even without code intervention. We offer support on LiteSpeed ​​Enterprise, with all the advanced features (including ESI cache, automatic crawlers, smart purge), and Open Lite Speed, for leaner or free-licensed environments. We address issues related to licensing, listener management, integration with cPanel/Plesk or DirectAdmin, and custom configuration of cache profiles for e-commerce sites, publishing sites, or portals with seasonal traffic.

In addition to pure configuration, we provide tools for analysis and monitoring, such as tracking response times by location, checking generated status codes, and proactively analyzing error logs, helping customers prevent bottlenecks, configuration errors, or application vulnerabilities.

In any case, our goal is not to “get the server working”, but make it perform to the maximum, guaranteeing reliability, speed and coherence with the real needs of the web project.

Multi-tier caching systems: Varnish, Redis, OPcache

We are convinced that Performance optimization should not be limited to the application level, but must involve the entire technological chain, from the HTTP server to the database, passing through all the caching layers. For this reason We support our customers in the design and configuration of multi-level caching systems, custom-built based on the architecture, expected load and user behavior.

Varnish cache It often represents the first line of defense against slowdowns. When configured correctly, it allows you to serve content directly from RAM, drastically reducing interaction with the backend and therefore the response time perceived by the user. The heart of Varnish's efficiency is the file default.vcl, which we write and customize to accommodate dynamic behavior, authentication, cache exceptions, and purging logic. Using advanced directives like hit_for_pass, grace mode, backend health checks and conditional cookie management, we can achieve extremely granular caching policies, also compatible with complex e-commerce or editorial portals with high update frequency.

In environments where application-side performance is critical, Redis plays a central role. We use it as object cache for WordPress, as a session handler for PHP, and as a backend cache for repetitive queries. We can configure Redis in single-instance or replicated mode, with ACL protection, passwords, separate namespaces for different environments, and advanced metrics monitoring. For high-load environments or high-performance multicore systems, we offer KeyDB as an alternative to Redis, thanks to its native multi-threaded architecture, wire-protocol compatibility with Redis, and built-in support for useful features such as multiple authentication and native TLS support.

Another often overlooked but fundamental element is OPcache, the PHP module that manages the bytecode cache. Its configuration directly impacts PHP page response times and interpreter stability. In shared or highly concurrent environments, a poorly configured OPcache can cause difficult-to-diagnose problems, such as cache fragmentation, memory leaks, or intermittent errors. Our PHP-FPM tuning always includes an analysis of OPcache parameters., as opcache.memory_consumption, opcache.interned_strings_buffer, opcache.validate_timestamps e opcache.revalidate_freq, in addition to periodic monitoring of runtime behavior to avoid saturations or anomalous behavior.

To these standard caching levels, we can add custom strategies, such as microcaching on NGINX, ESI caching with LiteSpeed, reverse proxy with custom TTL rules, and coordination with external CDNs. In every project, the goal is to build a coherent caching chain, capable of scaling without compromising the dynamics of the content and without forcing developers to make architectural sacrifices.

Optimization and support for MySQL, MariaDB, and Percona Server databases

One of the areas in which we are most often involved is the relational database management and optimization, with particular attention to MySQL, MariaDB e Percona Server for MySQL, three solutions widely adopted in both enterprise and mid-level production environments.

Our work is not limited to a simple file review my.cnf, but understands a systematic analysis, tuning and consolidation activity, always conducted with a scientific approach and without empirical intervention. We start by collecting key metrics—I/O rates, queries per second, disk temporary tables, buffer pool status, query cache, and thread concurrency—to identify bottlenecks and inefficiencies that often escape superficial monitoring.

We take care of theslow query optimization, through tools such as EXPLAIN, ANALYZE, SHOW PROFILE, slow_query_log e pt-query-digest, with the aim of reducing the computational load without directly intervening on the application code. Where possible, we also intervene on the index structure, identifying duplicates, redundancies or strategic gaps.

The analysis extends to the evaluation of themost suitable engine for each tableWhile InnoDB is the default choice in most cases, we know when MyISAM may be preferable for bulk reads or when to introduce specialized engines including TokuDB o myrocks for write-intensive workloads with advanced compression.

Another area where we provide support is the database replication, both in traditional master/slave mode and via GTID-based replication, semi-synchronous, or multi-source. We also work on configurations with circular replication or read-only scaling, always with the goal of improving scalability and ensuring high availability.

In terms of backup management, we recommend and configure appropriate tools based on your environment: xtrabackup for hot snapshots and incremental backups, mysqldump o mysqlpump for test and development environments, and mysqlbinlog for point-in-time recovery in critical scenarios. We offer customized differential or full backup strategies, with compression, encryption and integrity verification, and scheduling via cron or orchestration tools.

We are also often involved in complex migrations between versions or between different engines, including transitions from MySQL to MariaDB or Percona Server, in environments with high uptime and compatibility constraints. In these cases, we take care of the pre-migration analysis phase, temporary replication of the environment, compatibility testing, and fallback documentation in the event of a rollback.

In all our interventions, the focus is always the same: get the most out of your database, in terms of stability, speed, and the ability to scale without compromising data integrity. And above all, we do so with a keen eye on future maintenance, configuration sustainability, and operational clarity for internal teams.

Control Panels: Plesk, cPanel, DirectAdmin

Many of our customers use control panels to simplify the daily management of your servers, especially in multi-user, multi-domain, or reseller environments. However, even these tools, although designed to facilitate administration, require advanced system skills to be fully exploited, maintained safely and adapted to real production contexts.

Su Plesk, one of the most popular platforms in the professional market, we regularly intervene on aspects that go beyond the options available via the graphical interface. We deal with system resource optimization, refining PHP-FPM's behavior, customizing domain limits, and adjusting caching and compression settings. Let's configure complete multi-PHP environments, with legacy versions for compatibility and modern versions for performance, ensuring separation between staging and production environments. We also optimize NGINX in reverse proxy mode, enabling custom configurations for headers, static files, fallbacks, and additional security protections. For email, we support the implementation of advanced policies on Postfix, DNS-based DKIM, SPF in multi-IP environments, and customize spam filters. We also resolve conflicts related to external modules or custom integrations, often undocumented.

With cPanel and WHM, instead, we move with great familiarity on all the components: Apache + PHP-FPM, MySQL / MariaDB, Exim/Dovecot e CloudLinux, the latter being very popular for efficient resource management in multi-tenant environments. We perform targeted tuning on LVE, CageFS, PHP SelectorWe configure WHM to limit abnormal CPU, RAM, or process consumption. We customize DNS templates (zone templates), manage multi-nameserver DNS routing, and implement active monitoring with custom scripts that automatically intervene on critical events. In addition, we perform deep cleanup operations, updating WHM/cPanel modules in dated environments and complete server-to-server migration, even with different versions.

DirectAdmin, finally, it is an increasingly popular choice among those who want a lightweight, fast and resource-efficient panel, especially in the VPS or cloud environment. In these contexts, we offer consultancy for advanced configurations, integration with external DNS, setup of DNS clusters (e.g. PowerDNS, MyDNS), fail2ban configuration, Exim/SpamAssassin tuning, and custom scripting. We also handle the automation of recurring tasks via hooks and post-creation scripts (pre/post user/domain creation), and integration with remote backup systems via rsync, SFTP, or S3-compatible object storage.

In any case, our control panel consultancy is not limited to installation or troubleshooting: We guide the customer towards solid, upgradeable and secure configurations, capable of scaling as traffic increases and truly simplifying work, without adding hidden complexity.

Linux Mail Systems: Postfix, Exim, Dovecot, Courier

We are particularly experienced in configuring, optimizing and securing Linux-based email servers., especially those based on Postfix o Exim like MTA, and Dovecot o Courier for IMAP and POP3 services. We work on both new installations and legacy systems, ensuring robust, secure management that complies with the latest deliverability standards.

We offer a complete and in-depth support, which covers both low-level technical aspects and operational implications related to delivery quality and IP reputation. Specifically:

• Correct configuration of SPF, DKIM and DMARC, with associated DNS management, aggregate (rua) and forensic (ruf) reporting analysis, and support in managing multiple domains, subdomains and multi-IP environments.

• Mail queue management with native tools (postqueue, postsuper, mailq) and advanced reporting via pflogsumm, postlogwatch or custom analyzers written in Bash or Python.

• In-depth log analysis (/var/log/maillog, exim_mainlog, dovecot.log) to identify delivery issues, SMTP errors, DNSBL blocks, bounces, and abuse attempts.

• Advanced Message Routing postfwd or conditional configurations in Postfix transport maps, useful for routing messages based on domain, content type, or priority, even across multiple relays.

• Protection from spam, malware and phishing through effective filters such as rspamd, SpamAssassin, amavis, often integrated with ClamAV for server-side antivirus scanning, also with centralized policy management.

• Implementation of active security policies, such as dynamic greylisting, throttling by IP or domain, rate limiting based on SMTP connections, per-user sending limit control, and checking for suspicious authentication.

We also deal with DNSBL blacklist management and IP reputation, supporting customers in identifying the cause of spam problems, removing them from blacklists (Spamhaus, UCEPROTECT, Barracuda, Proofpoint) and preventing future relapses through IP warm-up, controlled rotation and segmentation of mail flows.

In high volume environments or where it is necessary to separate transactional traffic from promotional traffic, we design separate outbound SMTP systems, with dedicated configurations for outgoing mail and the use of external relay providers (Amazon SES, Sendinblue, Mailgun, SMTP2Go, etc.).

We also provide full mail stack security consulting, managing:

• Mandatory TLS on all SMTP/IMAP/POP3 connections

• SASL Secure Authentication

• Multi-user access with domain separation

• Monitoring sending and receiving statistics

• Audit of compromised or spammed accounts

When necessary, we automate recurring tasks, such as queue cleanup, log rotation, stuck message notification, and checking for compliance with corporate policies on content, signatures, or sender domains.

Our goal is to offer a reliable, secure and easily maintainable mail infrastructure, both for small businesses with just a few accounts and for companies with high volumes and the need for continuous monitoring and regulatory compliance.

Linux System Security and Hardening

Security is one of the founding pillars of our systems consultancy. We don't consider it an add-on or an emergency intervention, but a continuous and structured process that must be planned, documented, and periodically verified. Our approach is based on multi-level hardening strategies, calibrated according to the type of infrastructure, the exposed surface area and the criticality of the service.

We apply custom configurations of SELinux e AppArmor, defining non-invasive yet effective policies, especially in RHEL, AlmaLinux, Ubuntu, and Debian environments. In highly sensitive contexts or subject to security regulations, we provide support for creating custom profiles and resolving application conflicts, often caused by overly permissive or overly restrictive policies.

We are experts in implementing and tuning tools such as Fail2Ban, auditd, logwatch, aide e psacct, For the early detection of anomalous activity, retroactive access analysis, and automated notifications via critical channels (email, webhooks, Telegram, Slack). We also design proactive security routines, such as file integrity verification, forced SSH key rotation, two-factor authentication via PAM, and differentiated access based on operational context.

In environments with public exposure or in the presence of sensitive data, we integrate systems IDS and IPS such as Snort, Suricata and OSSEC, with customized configurations and centralized logging. This allows us to react promptly to recognizable attack patterns, even in distributed or low-visibility environments.

One of our most requested areas of intervention concerns the Cloudflare advanced configuration, which we use not only as a CDN, but as multi-level intelligent protection barrierWe design custom WAF policies based on combinations of headers, URIs, geolocation and IP reputation, implement the Rate Limiting, Bot Management, and we leverage the cache to mitigate the effects of L7 attacks (HTTP floods). We also enable key features such as Automatic DNS failover, IP origin obfuscation and L3/L4 DDoS protection, useful in cases where customers do not have on-premises anti-DDoS solutions.

We also complete the intervention at the web server level, applying WAF policies based on ModSecurity for Apache, NGINX and LiteSpeed. We customize the OWASP Core Rule Set rules To adapt them to the application context, reducing false positives and enhancing protection against known exploits and zero-day vulnerabilities. In more dynamic environments, we configure regular rule updates, detailed logs, and automations for analyzing generated events.

Our goal is not simply to “protect the server”, but create a solid, verifiable and manageable security posture over time, capable of adapting to changing threats and the evolution of the infrastructure itself.

Backup, disaster recovery and business continuity

No infrastructure can be considered truly professional without a solid, consistent, and time-tested backup strategy. For this reason we accompany each server – physical, virtual or cloud – with a backup plan designed to minimize the risk of data loss, while ensuring rapid recovery, integrity and traceability of operations.

We use reliable and proven tools such as Borg Backup, Restic, Duplicity and more traditional solutions based on rsync via SSH tunnel, always with customized scripts to adapt to the specifics of the environment: database, file system, multimedia content or temporary files. Each backup routine includes clear retention policies, based on daily, weekly and monthly logic, with Automatic integrity verification and alerts in case of anomalies.

For customers operating in mission-critical industries or managing large amounts of data in ZFS environments, we design advanced snapshot systems based on OpenZFS. In particular, we implement Sanoid for automating local snapshots, with granular configurations on frequencies, retention policies, and rotation rules. We use Syncoid for remote replication of ZFS datasets, using the commands zfs send e zfs receive, which allow for secure, fast and incremental transfer even over WAN routes or encrypted networks.

This approach is particularly effective for distributed infrastructures, highly available Linux VPS, mission-critical storage environments, or multi-tenant hosting. The advantage of ZFS lies not only in the speed of snapshots and recovery, but also in the data integrity assurance thanks to checksums at every level, the possibility of instant rollbacks and native deduplication.

In all cases, our consultancy also includes designing comprehensive disaster recovery plans, with scenarios tested for the bare-metal restoration, asynchronous geographic replication, scheduled synchronization between datacenters e periodic testing of restores, to ensure that backups are not just scheduled, but actually usable in case of emergency.

Each project is carefully documented, both technically and operationally, so that the client knows exactly the methods, timelines, and procedures for a rapid and controlled data recovery.

Implementation and support on ZFS and OpenZFS

More and more customers are asking us for support in the implementation of advanced filesystems such as ZFS, aware of the added value it can offer in terms of safety, performance and reliability over time. In this context, Managed Server SRL is one of the few companies in Italy to provide direct technical consultancy on OpenZFS, even on complex and highly critical production environments.

OpenZFS It is much more than a filesystem: it is a integrated platform for data management, with native functionality of Instant snapshots, transparent compression, deduplication, remote replication, data corruption protection and advanced storage management. Its copy-on-write architecture ensures that every operation is traceable and reversible, making it ideal for both server and VPS environments, or backup and disaster recovery infrastructures.

We use ZFS in many production contexts, both for managing volumes containing critical files, and as a basis for containers, virtual machines, or entire hosting clusters. We implement solutions on AlmaLinux, Ubuntu, Debian and FreeBSD, taking care of compatibility, I/O performance and kernel-level parameter tuning.

We intervene in the Initial setup of ZFS pools, designing layouts with mirrored disks, RAID-Z1/Z2/Z3, or hybrid combinations depending on the balance between performance, redundancy, and capacity. We also integrate monitoring and alerting systems for SMART disk health and potential pool degradation.

To ensure an effective versioning and recovery strategy, we automate the creation of recurring snapshots via cronjob or Sanoid, with customized retention policies for each dataset. We also manage the asynchronous data replication with Syncoid, using zfs send e zfs receive for encrypted incremental transfers over the network, even between different geographical nodes or through SSH tunnels.

In high-density hosting environments or private clusters, we also leverage ZFS to provide container isolation, log compression, application resource separation, and separate snapshots for each tenant.

Thanks to our experience, we can adapt ZFS to any context, balancing performance needs with structural solidity, and providing documentation, verification tools and operating procedures that make the use of the filesystem sustainable in the long term even for non-specialized teams.

Choosing ZFS with the right configuration means invest in the resilience of your data, in an era where risks related to file loss, corruption, or integrity are increasingly common. And we are ready to guide clients on this journey with expertise and attention to detail.

Automation, monitoring and scripting

Our strength also lies in our ability to automate system tasks, creating tools that reduce errors, standardize processes and ensure operational continuity even in critical environments.

We write custom Bash and Python scripts, designed for tasks such as backups, process and service monitoring, advanced log parsing, anomaly notification via email, webhooks, Telegram, or other alert channels. In many cases, we develop lightweight and independent tools, designed to work even in the absence of external agents or tools, which cyclically analyze log files, system metrics, command output such as systemctl, netstat, iostat, df, uptime o mysqladmin, and perform automatic corrective actions when predefined thresholds are exceeded.

In addition to custom solutions, we also configure and manage centralized monitoring systems For more complex infrastructures, with multiple servers, clusters, distributed VPS, and hybrid environments. We support platforms such as:

• netdata, for real-time monitoring with continuous metric collection, immediate graphical display and threshold alarms;

• Zabbix, for enterprise environments that require distributed monitoring, advanced alerting, automatic discovery, and integration with external systems;

• Nagios, with customized configurations and ad hoc plugins, useful in contexts where maximum compatibility and flexibility in checking services are required;

• CheckMK, in the Raw or Enterprise version, for those who want a powerful and centralized platform, with granular checks, accessible dashboards and tools for historical analysis;

• ELK Stack (Elasticsearch, Logstash, Kibana), for centralized log collection, event tracking, audit trails, and correlation between metrics and system or application logs.

Based on the complexity of the environment and the level of autonomy of the client, we propose hybrid architectures, where our local scripts work in parallel with centralized systems, providing a double level of control: one immediate and reactive, the other analytical and aggregate.

All the solutions we develop or configure are designed to be sustainable over timeWe document every procedure, structure files in a readable manner, adopt consistent naming conventions, and make the system easily maintainable, even by non-specialist personnel. Where possible, we provide automatic update tools and reusable templates to quickly extend coverage to new nodes or services.

Our goal is to enable the customer to prevent problems before they arise, minimizing reaction times and facilitating the work of technical teams, thanks to reliable, integrated and fully controlled tools.

In short: we are much more than a hosting provider

Managed Server SRL is not just a hosting company. We are first of all a team of specialized Linux consultants, with a long experience on production systems, mission-critical databases, high-availability environments, and complex infrastructures, often distributed across different datacenters, public clouds, and on-premise physical servers.

We accompany digital agencies, developers, software houses, IT companies and system integrators in the daily management of your server environments, offering ongoing technical support, customized solutions, and high-level systems consultancyWe intervene where practicality is needed: in troubleshooting an unstable database, in designing a high-availability cluster, in optimizing a system that can't handle traffic, or in securing a server exposed to real threats.

Our approach is direct and operational: we don't just advise, we work on the systemsWe analyze logs, test solutions, automate processes, and work closely with both internal and outsourced infrastructure managers.

Anyone who visits our homepage sees a high-performance hosting provider. But whoever goes further and starts collaborating with us, discovers a reliable, competent, present technical partner, able to face and solve real, complex and often overlooked problems by those who limit themselves to standard management.

We are always on the customer's side. Because Our job is not to sell disk space, but to ensure continuity, efficiency and quality in the management of Linux systems., regardless of datacenter, platform, or initial configuration.
