There are three different ways to deal with obsolete components.
1. Upgrading does not change technology
Invest in existing on-premises IT infrastructure and make necessary upgrades.
2. Upgrade with technological change
Think of outdated components as an opportunity to move your servers, applications, and workloads to the cloud without significantly changing applications and underlying infrastructure.
3. Upgrade through a complete modernization of the application architecture
View outdated components as an opportunity to modernize servers, applications, and workloads from the ground up using cloud services. Through this transition to the cloud, you'll save on IT costs and benefit from the increased efficiency of your applications and processes.
