In the light of recent geopolitical events, DDoS attacks on information systems hosted in Russia have multiplied. The increased number of attacks was reported by reliable media citing trusted sources in the Ministry of Digital Development of Russia.
In such circumstances, disaster recovery services can help to ensure the continuous functioning of business systems. Right now, a DRaaS solution based on a cloud located in Europe can minimize the risks of cyberattacks. That’s why we call Linx Safe a smart move in the current business realities.

Don't stop me now  

24x7x365 business operations face both traditional and new challenges on the IT infrastructure level.

In addition to human factors and equipment maintenance, new challenges include frequent hacker activity, geopolitical risks, and the availability of human resources and competencies.

Among the many ways to address such challenges, cloud backup and disaster recovery (DR) solutions for data and IT systems are on the rise.
There are two main models for implementing such a solution.

Project vs. Product 

A project-based approach to DR implies a custom-built system designed by IT service providers based on customers’ tasks and conditions. The project takes time to plan, implement, test, and launch, followed by continuous technical support.

Another approach is product-based, which means the using a ready-made IT product for solving business problems needs. The product is ready to run in different IT infrastructures, which means a business can immediately benefit from it and bypass the shortcomings of custom-built solutions.

Those options work for their respective customer audiences. So far, the project-based approach to full-fledged backup and disaster recovery prevails on the Russian IT market.

Both options solve the tasks for different groups of customers. However, the product-based approach to Backup&DR is the future — and here’s why:

A new market emerges  

Even though the Russian market of cloud products and services lags behind in terms of standards, it’s showing notable growth. An ecosystem of services for business and government is being actively formed.

The market is still on the way to maturity, and the client demand for cloud products isn’t always met by the existing range of IT services. A project-based approach, which implies the creation of custom solutions from the components available on the market, doesn’t fit the fast-growing demand for Backup&DR.

The market needs ready-made solutions which can be deployed quickly and ensure the uninterrupted operations of IT systems. Since 2017, the market for DR solutions in Russia has grown 6 times, and the core advantage of the product-based approach is the ability to maintain such a pace.

Safe for data and applications  

The Linx Safe disaster recovery product was developed with a deep understanding of market trends to meet the growing demand for protection of IT systems and data from infrastructure failures. Linx Safe consists of three services, created and developed by Linxdatacenter as high-end independent solutions: Cloud Connect, DRaaS, and the global cloud connectivity.

Cloud Connect is a direct dedicated channel between the components of a business IT system. It guarantees connectivity regardless of global internet failures and IP blocks.

Disaster recovery-as-a-service (DRaaS) makes it possible to create twins of physical and virtual servers and run them in the backup cloud to immediately reroute traffic in case of an accident. Automation reduces recovery time and mitigates the risk of human error, minimizing business losses from infrastructure failures.

The last component of Linx Safe is the cloud resources provided by Amazon Web Services (AWS).

The combination of these services allowed Linxdatacenter to create a product that meets the core requirements of modern businesses. It mitigates the risks related to the functioning of the internet and interruptions in the supply of imported IT infrastructure components, and meets customers’ need for stable connectivity with customers from the global West.The future We constantly collect statistical data to analyze the performance of the first version of Linx Safe. Further development will be based on the insights and findings collected from the initial period. From a purely technical perspective, we’re researching options to establish compatibility with another backup cloud, for instance, with a platforms located in China.

The architecture of reliability 

The functioning of Linx Safe is organized as follows: The connection to the AWS platform is established through direct channels to traffic hubs in Frankfurt and Stockholm.
Linxdatacenter engineers set up a secure connection to AWS for data replication.

A sequence of actions is developed and followed to establish the necessary IT infrastructure in a global cloud.

This digital twin will be immediately enabled in case of an incident and can be used for testing purposes. Linx Safe is a full-fledged backup and recovery product that includes training for the client’s IT specialists and 24x7x365 technical support and consulting in Russian and English.

Target audience 

Linx Safe meets the needs of various groups of clients. It’s most relevant for customers with a critical need for replication of data and infrastructure, such as game developers (Game Dev).
It also meets the typical requirements of the EdTech segment, which needs continuous availability of resources and services.

Linx Safe works great for both web and mobile applications. It also ensures the interrupted operation of critically important IT infrastructure for large businesses in any field, such as banking, trade, industry, logistics, etc. How to get started To get started with Linx Safe, the company needs an agent software on its servers which can be located in any datacenter, public cloud, or on-premises at the client’s place of business. The product works with any volume of data and with almost any set of applications.

 

The future  

We constantly collect statistical data to analyze the performance of the first version of Linx Safe. Further development will be based on the insights and findings collected from the initial period.

From a purely technical perspective, we’re researching options to establish compatibility with another backup cloud, for instance, with platforms located in China.

Data center is a complex IT and engineering object, which requires professionalism at all levels of management: from managers to technical specialists and executors of maintenance works. Here's how we helped our client put operational management in corporate data centers in order.  

Management is in the lead 

The most advanced and expensive IT equipment will not bring the expected economic benefits if proper processes of engineering systems operation in the data center, where it is located, are not established.  

The role of reliable and productive data centers in today's economy is constantly growing along with the requirements for their uninterrupted operation. However, there is a big systemic problem on this front.  

A high level of "uptime" - failure-free operation of a data center without downtime - depends very much on the engineering team that manages the site. And there is no single formalized school of data center management.  

And there is no single formalized school of data center management.    

Nationwide  

In practice, the situation with the operation of data centers in Russia is as follows.  

Data centers in the commercial segment usually have certificates confirming their management competence. Not all of them do, but the very specifics of the business model, when a provider is responsible to the client for the quality of service, money and reputation in the market, obligates them to own the subject. 

The segment of corporate data centers that serve companies' own needs lags far behind commercial data centers in terms of operational quality. The internal customer is not treated as carefully as the external customer, not every company understands the potential of well-configured management processes. 

Finally, government departmental data centers - in this regard, they are often unknown territory due to their closed nature. An international audit of such facilities is understandably impossible. Russian state standards are just being developed.  

This all translates into a "who knows what" situation. "Diverse" composition of operation teams composed of specialists with different backgrounds, different approaches to the organization of corporate architecture, different views and requirements to IT departments.  

There are many factors that lead to this state of affairs, one of the most important is the lack of systematic documentation of operational processes. There are a couple of introductory articles by Uptime Institute which give an idea of the problem and how to overcome it. But then it's necessary to build the system by your own efforts. And not every business has enough resources and competence for that.  ⠀⠀  

Meanwhile, even a small systematization of management processes according to industry best practices always yields excellent results in terms of improving the resilience of engineering and IT systems.  

Case: through thorns to the relative order 

Let's illustrate by the example of an implemented project. A large international company with its own data center network approached us. The request was for help to optimize the management processes at three sites where IT systems and business-critical applications are deployed.  

The company had recently undergone an audit of its headquarters and received a list of inconsistencies with corporate standards with orders to eliminate them. We were brought in as a consultant for this as a bearer of industry competence: we have been developing our own data center management system and have been educating on the role of quality in operational processes for several years.  

Communication with the client's team began. The specialists wanted to get a well-established system of data center engineering systems operation, documented on the processes of monitoring, maintenance and troubleshooting. All this had to ensure optimization of the infrastructure component in terms of IT equipment continuity.  

And here began the most interesting part.  

Know thyself 

To assess the level of data centers in terms of compliance with standards, you need to know the exact requirements of the business to IT systems: what is the level of internal SLA, the allowable period of equipment downtime, etc.  

It became clear right away that the IT department did not know exactly what the business wanted. There were no internal criteria of service quality, no understanding of the logic of their own infrastructure.  

Colleagues simply had no idea what the permissible downtime for IT-related operations was, what the optimal system recovery time in case of a disaster was, or how the architecture of their own applications was structured. For example, we had to figure out whether a "crash" of one of the data centers would be critical to the application, or if there were no components affecting the application.  

Without knowing such things, it is impossible to calculate any specific operational requirements. The client recognized the problem and increased coordination between IT and the business to develop internal requirements and establish relationships to align operations.  

Once an understanding of the IT systems architecture was achieved, the team was able to summarize the requirements for operations, contractors, and equipment reliability levels.  

Improvements in the process 

Our specialists traveled to sites to assess infrastructure, read existing documentation, and checked the level of compliance of data center projects with actual implementation.  

Interviews with the responsible employees and their managers became a separate area of focus. They told what and how they do in different work situations, how the key processes of engineering systems' operation are arranged.  

After starting the work and getting acquainted with the specifics of the task the client "gave up" a little: we heard the request "just to write all the necessary documentation", quickly and without deep diving into the processes.  

However, proper optimization of data center "engineering" management implies the task to teach people to properly assess the processes and write unique documentation for them based on the specifics of the object.  

It is impossible to come up with a working document for a specific maintenance area manager - unless you work with him at the site continuously for several months. Therefore this approach was rejected: We found local leaders who were willing to learn themselves and lead their subordinates.  

Having explained the algorithm of documents creation, requirements to their contents and principles of instructions ecosystem organization, for the next six months we controlled the process of detailed writing of documentation and step-by-step transition of the personnel to work in a new way. 

This was followed by a phase of initial support for work on the updated regulations, which lasted one year in a remote format. Then we moved on to training and drills - the only way to put the new material into practice.  

What's been done 

In the process, we were able to resolve several serious issues.  

First of all, we avoided double documentation, which the client's employees feared. To this end, we combined in the new regulations the regulatory requirements applied to various engineering systems as standard (electrics, cooling, access control), with industry best practices, creating a transparent documentation structure with simple and logical navigation.   

The principle of "easy to find, easy to understand, easy to remember" was complemented by the fact that the new information was linked to the old experience and knowledge of the employees. 

Next, we reshuffled the staff of service engineers: several people turned out to be completely unprepared for the change. The resistance of some was successfully overcome in the course of the project through the demonstration of benefits, but a certain percentage of employees turned out to be untrained and unresponsive to new things.  

But we were surprised by the company's frivolous attitude to its IT infrastructure: from the lack of redundancy of critical systems to the chaos in the structure and management.  

In 1.5 years the engineering systems management processes have been pumped up to the level that allowed the company's specialists to successfully report "for quality" to the auditors from the headquarters.  

With the support of the operating component development pace the company will be able to pass any existing certification of data centers from leading international agencies.  

Summary 

In general, the prospects of consulting in the field of operational management of data centers, in our opinion, are the brightest.  

The process of digitalization of the economy and the public sector is in full swing. Yes, there will be a lot of adjustments in the launch of new projects and plans for the development of old ones, but this will not change the essence - the operation should be improved at least to improve the efficiency of already built sites.  

The main problem here: many managers do not understand what thin ice they are walking on, not paying proper attention to this point. The human factor is still the main source of the most unpleasant accidents and failures. And it needs to be explained.  

Government data center projects are also becoming more relevant now and require increased attention in terms of operations: the scope of government IT systems is growing. Here, too, the development and introduction of a system of standardization and certification of sites will be required.  

When the requirements to public data centers in Russia at the level of legislation will be reduced to a standard, it can be applied to commercial data centers, including for the placement of public IT resources.  

The work in this area is ongoing, we are participating in this process in consultation with the Ministry of Digital and by building competencies for teaching courses on data center operation at the ANO Data Center. There is not much experience on such tasks in Russia, and we believe that we should share it with colleagues and clients.

business challenge

The customer faced a technical issue with a persistent BGP session flag with Linxdatacenter hardware. We examined the problem and found out that one of customer’s hosts was under a DDoS attack.

Because of the distributed nature of the attack, traffic couldn’t be filtered effectively, and disconnecting the host from the external network wasn’t an option. The attack stopped after changes in the server configuration, but resumed the day after. A 5.5 Gbps attack overloaded the junctions with internet providers, affecting other Linx Cloud users. To mitigate the effects of the attack, we employed a dedicated DDoS protection service.

Solution

To ensure the continuous availability of resources hosted in Linx Cloud, we rerouted all the customer’s traffic through StormWall Anti-DDoS system. The attack was stopped within half an hour. To prevent future cyberattacks, we organized all connections to the customer’s resources through the StormWall network.
