System components with outdated software or hardware without maintenance represent a significant operating risk in growing IT infrastructures: For example, in the absence of maintenance, there is no longer manufacturer support in the event of a malfunction. The reliability of IT systems also decreases, which reduces innovation. And finally, significant security risks arise because the necessary system patches are not available. Business continuity management requires companies to find a smart way of dealing with the end-of-life of IT components. The use of the latest cloud technologies can make IT infrastructure management much easier.
The basic options for dealing with the end of life of IT components are demonstrated by the example of the PostgreSQL 9.6 database:
1️⃣ Upgrade without changing technology:
Invest in your existing on-premises IT infrastructure and perform necessary upgrades.
2️⃣ Upgrade with Technology Change:
View Outdated Components as an opportunity to migrate your servers, applications, and workloads to the cloud without significantly changing the application and underlying infrastructure.
When upgrading, regardless of the scenario, keep in mind that a major version change usually changes the internal format of system tables and data files. These changes are often complex. So backward compatibility of all stored data often cannot be maintained. Major upgrades regularly require a dump/reload of the database. Although upgrading one major version to another is possible without upgrading the intervening versions, it is recommended to carefully evaluate the release notes of all intervening major versions to see if they impact the application. Thus, upgrading a major version is fundamentally riskier than upgrading an intermediate version, resulting in both planning, testing, and execution being more costly.
3️⃣ Upgrade with a complete modernization of the application architecture:
See Outdated Components as an opportunity to modernize your servers, applications, and workloads from the ground up with cloud services. With this transition to the cloud, you will save IT costs and benefit from the growing efficiency of your applications and processes.
