Infrastructure

IT Infrastructure operating the digital side of your organization can be the basis of your actual operations or represent a significant part of these operations. There are several choices you can make regarding your server or serverless infrastructure, the use of the cloud. The way your software and programs run on your chosen infrastructure can also be configured with containers and microservices or hosted directly on virtual machines. Several options to set up your digital assets exist. The DevOps team, together with a solution architect from TravoLab can discuss this range of options, make a selection, provide a detailed cost estimate and implement the target architecture of your digital core.

Business owners might look for a change in the existing infrastructure because of a few reasons:

  • Performance – applications are not operating as fast as they should
  • Costs – prices for IT infrastructure keep going up with no obvious reason
  • Deployment speed – it takes staff a lot of time to manually setup servers and install the software
  • Security – sensitive data is not very well protected and a patch is required against the vulnerabilities that have been uncovered

Travolab has a team of DevOps experts capable of assessing your IT environment and drawing a clear roadmap for the infrastructure transformation or improvement and cloud services adoption.

We will take a detailed look at the current architecture of your IT infrastructure, will identify how services are operated and the resources utilized and will suggest improvements to your current set up

Some problems can be solved by moving away from on-premises and migrating infrastructure to the cloud, unlocking a number of advantages by doing so. The nature of your business needs will dictate the right approach.

Cloud computing

In Europe competitions occurs mostly among the three main providers: Microsoft Azure, Google Cloud Platform and Amazon Web Services. Local players, such as France-based OVH Cloud may have a competitive edge because they are considerably less expensive and better able to serve more specific needs in areas such as privacy and security.

Cloud computingThe ones looking for a price lower than OVH, can consider hosting providers like Soyoustart and Kimsufi, which servers are the previous generation used by OVH.

TravoLab specialists can suggest the cloud provide most suitable for your business needs and make the necessary setup of the cloud computing resources.

Cloud computing

Commercial cloud providers offer computing resources to clients in various forms:

  • Physical servers (Bare Metal)
  • Virtual dedicated servers (VDS) or virtual private servers (VPS)
  • Virtual machines (VM)
  • Containers
  • Serverless functions

We have experience of building the IT infrastructure with all the ingredients specified above.

Bare Metal

Are single-tenant, physical server which reside in the highly secure datacenters and are entirely dedicated to one customer who pays for them. However, the customer is responsible for the server maintenance: selecting hardware and installing software.

Virtual Dedicated (VDS)

Offer the same single-tenant isolation and the same control over workload and performance, but it is not always coupled with a specific physical machine. A re-booted VDS could end up located on a new physical machine potentially in a different physical location. When some CPU cores are dedicated for the virtual server, then it is dedicated and called VDS. Otherwise, it is being private without dedication of computing power and is call VPS. Buying a virtual server gives the possibility to get an own virtual server environment with less headaches related to the ownership and maintenance of the bare metal server itself.

Hypervisor

On top of the bare metal hardware or virtual dedicated server it is possible to place any software, but usually tool is a hypervisor. It allows to separate the server’s operating system and applications from the hardware. Then, the bare metal server or virtual dedicated server can be divided into several independent servers, called virtual machines. Virtual machines can be easily cloned or moved to another location.

TravoLab DevOps are trained to build and deploy a large number of virtual machines and manage such an environment on VMware and Proxmox (open source) solutions

Virtual MachinesVirtual Machines

Creating a virtual machine (VM) with the help of the cloud service management console or API can be done rapidly. A Virtual machine can be easily turned off when it is not any more required . Cloud providers keep track of the amount of resources your services use inside your virtual machines and this is going to be the base on which they provide their billing . If there’s a problem with hardware, cloud service providers migrate themselves your VM to another physical server.

However, in most cases your virtual machines will have to share the common physical infrastructure with other multiple users. This is public or multi-tenant approach: if an active neighbor on the physical server is running intensive data processing, there is reduced power available to you. However, for an additional price some providers can offer guaranteed computing power.

Containers

Containers are a lighter-weight, more agile way of handling virtualization – since they don’t use a VM hypervisor, they provide faster resource provisioning and speedier availability for your applications.

Containers – a good method of running and transporting applications safely between different IT environments. With containerization, each microservice is packaged as one or more Docker container, which can be quickly and easily deployed on any environment with consistent results. Orchestrators like Kubernetes are used to manage large groups of containers.

You might be interested in one of the core advantages provided by containers technology – portability. By containerizing your services, Travolab engineers make your project code portable across on-premise VMs, bare metal, and multiple cloud provider environments.

Functions

Serverless computing is one more step beyond virtualization. Functions are single-purpose pieces of code executed in response to the events. You are charged based on the number of requests for your functions and the time it takes for your code to execute. Thus, using functions you pay only for what you use, eliminating the need for monthly server rent, software and hardware management.

Cloud Portability

Travolab specialists will suggest you the optimal cloud provider and server configuration, however your company might be interested in an easy migration from one cloud provider to another in response to a price increase or a breached service-level agreement.

Another reason to change cloud provider may be the need to quickly create from scratch an additional region of presence for your applications and services, therefore providing a fast response to traffic from the target geographical location.

Cloud portability means the ability to move applications and data from one cloud computing environment to another with minimal disruption.

TravoLab experience in this area assumes that one of the keys of the fast and successful cloud migration is to consider and keep your infrastructure as a code.

Infrastructure as a Code

Public cloud providers are used to dynamically provision resources for the deployments.

Thus, DevOps have a possibility to describe the desired infrastructure in the set of configuration files. Once service parameters are defined in the files, devOps run scripts, and the IaC framework builds the cloud infrastructure automatically.

Infrastructure as Code is the process of provisioning and configuring an environment through code instead of manually setting up the required devices and systems.

Describing your infrastructure as a code helps standardize your software development life cycle and, in some cases, reengineer your application making it more robust and scalable.

The experience of TravoLab in IaC comes from using the utilities such as: Terraform, Docker, Ansible and Cloud-config

Recovery, Back-up, and Restoring

Indeed, data loss is one of the worst outcomes for enterprises of all sizes.

Recovery, Back-up, and Restoring

While putting in place the customer IT

infrastructure the , TravoLab engineers usually follow the “3-2-1″ backup rule which says: “There should be at least three copies or versions of data stored on two different pieces of media, one of which is off-site”. This approach serves the TravoLab customers well.

Recovery isn’t just about the ability to get services and their data back, it’s also about getting it all back quickly. By storing the customer’s infrastructure as a code, TravoLab DevOps team is capable to recover it literally within minutes.

Monitoring, Alerting, Logging

Monitoring is essential to businesses to ensure a necessary system is up and running.

Instead of waiting for a problem to occur, Travolab engineers create alerts to warn you when an anomaly is detected, helping you prevent problems before they occur.

We keep monitoring data separately from applications and services and centralize this information to ensure clients have easy access. Server monitoring metrics we consider: hardware utilization, server uptime, average response time, requests per second.

Continuous Integration and Delivery

Continuous Integration is the practice of integrating changes from different developers in the team into a mainline as early as possible, in best cases several times a day. This makes sure the code individual developers work on doesn’t divert too much.

Continuous Delivery, in its turn, automates the delivery of applications to selected infrastructure environments once the developer feels the code is ready to ship – this could be test, staging or production environments.

Once you’ve decided to adopt continuous deployment process, you’ll need to have several pieces of automation in place. Travolab DevOps can help you setup the GitLab / Jenkins delivery pipelines including the code build, the implementation of tests for Quality Assurance (QA tests) and the deployment of artifacts to the production server.
