Terraform and Infrastructure as a Code (IaaC)

Our technology stack.

During the presentation of applications of the cloud environment, we can often see services that are created by “clicking-through” a graphical interface. Everything happens quickly and impressively, it is visually attractive and attracts our attention. In practice, however, such a method of managing the infrastructure in the cloud has some very significant disadvantages.

t takes a long time to build multiple environments, and in most cases, discrepancies are unavoidable, and errors are hard to detect. The solution is using IaaC tools describing the IT infrastructure as a code. The code automates building the environment, ensuring environment consistency and repeatability. An additional advantage is a possibility of versioning the code, thanks to which we always have access to the history of changes.

When building infrastructure in the cloud for our clients, we always describe the infrastructure with code following good practices of creating and administering such environments. In most cases, we use for this purpose Terraform, but at the client’s request, we also incorporate native tools delivered by cloud environment providers.

Other Technologies

Application development in serverless technologies

When building serverless solutions in a cloud environment on a daily basis, we use Python and Go languages. Serverless services allow you to use cloud resources in the most optimal way so you can pay only for what you use (pay-as-you-go) by getting rid of performance limitations.

CI / CD processes

The Continuous Integration and Continuous Delivery tools allow building a process of uninterrupted software deployment in the server environment. Well-prepared systems make it possible to test and implement even several thousand changes a day in a way that is unnoticeable to the customer. There are various CI/CD tools available on the market today, the choice of which depends on many factors.

Apache, Nginx, and other web tools

Web technologies allow access to services and websites through browsers. The most common web servers are Apache, Nginx, and IIS. Many other additional components are used around these servers to ensure the availability and speed of websites.

Kafka and streaming/queuing systems

Streaming and queuing systems are used to exchange information between different elements of the IT system. They are especially helpful in microservice environments that use publishing and subscribing mechanisms to ensure that messages reach their recipients. Queuing systems can also be used to prevent message loss, which happens when messages end up on highly loaded back-end services.

Databases, data storage and analysis

Companies collect and process huge amounts of information. The method of data storage, speed of access and possibility of making analyses are essential for business development. Databases have evolved over the years. To obtain the best results, we must carefully select the technology depending on the amount and growth of data, access time, or their structure.

Ansible, automation and system orchestration

Automation and system orchestration tools support the management of server groups, especially when IT environments use automatic scaling mechanisms. Automation and orchestration tools will ensure consistency of environments and their configuration, so you can focus on your business.

Kubernetes, Docker and other technologies related to containerization

Containers with a set of tools for their management and application deployment are an indispensable element used to build modern microservice environments. Compared to monolithic large applications, microservice environments are more reliable as well as easier to develop and scale.

Cloud environment and cloud technologies

The cloud environment is an infrastructure distributed all over the world that provides access to IT services under the pay-as-you-go model. The cloud environment enables the rapid development of applications using ready-made solutions. They guarantee the highest security standards and automatic adaptation of resources to customer needs. For many companies, this solution is one of the most important factors contributing to their success.
