Modernization
Cloud and containers: modernize where your system runs
Not every modernization starts by rewriting code. Sometimes the urgent part is leaving servers that are reaching end of life, putting deployments in order or being able to scale. We move existing applications to the cloud or to containers with a plan per application.
The problem
Old servers, manual deployments
Applications installed by hand on servers nobody wants to touch, with no test environments equivalent to production and upgrades that depend on a single person. The risk grows even if the code works.
How we do it
From fragile servers to repeatable infrastructure
A decision per application
For each application we decide whether to rehost it as is, adjust it to run in containers, or rebuild it.
Containers and automated deployment
Container packaging, reproducible environments and automated deployments, so releasing stops being a risky event.
Public, private or hybrid cloud
The target is chosen by cost, regulation and operations: public cloud, private cloud or your own infrastructure with Red Hat OpenShift.
Staged migration
Applications move in waves, and each one is tested in the new environment before traffic is moved.
Illustrative scenario
Several Java and .NET applications on in-house servers
Imagine a company with several Java and .NET applications on physical servers whose support contract expires next year.
- The assessment classifies each application: which move as is, which are adjusted for containers and which one is worth rebuilding.
- The first applications are packaged in containers and deployed in the new environment alongside the current ones.
- Each application is tested in the new environment before its users are moved.
- The physical servers are switched off once they no longer serve traffic.
Illustrative scenario: A hypothetical example to explain the method: it does not describe a client or a measured result.
What you keep
Infrastructure you can repeat
Environments defined as code, automated deployments and operations documentation, so your team, or ours, can maintain it.
Frequently asked questions
Do I have to rewrite my application to move it to the cloud?
Not always. Many applications can be rehosted or adjusted for containers; the assessment shows when rewriting is actually worth it.
Do you work with a single cloud?
No. The target is decided per application: public, private or hybrid cloud, including your own infrastructure with Red Hat OpenShift.
Can it be combined with module-by-module migration?
Yes. One possible path is to move the current application to containers first and then rebuild its modules with the seven-phase method.
