Key Components in Application Modernization
Businesses often complain that enhancements to applications are often too technical and that as a consequence, business objectives are compromised. When attempting to modernize business applications, it’s important to clearly identify the value- adds and business objectives before launching into application modernization.
A recent TechTarget article explains how to deploy application modernization for business goals centralized in cost effectiveness, agility and security.
Continuous improvement and continuous delivery should always lead modernization efforts. Gradual implementation allows users to test the validity and usefulness of updates to ensure deployment is carried out successfully and that ROI is realized from the efforts from IT and DevOps.
DevOps for Cost Effectiveness
When costs are the primary concern in modernization, DevOps should handle deployment. DevOps will also make the assessment for which applications get deployed or re-deployed. They do so through componentization.
Componentization simply put, is the process that takes apart software systems into smaller, identifiable pieces. Microsoft describes it as a process to reduce your software footprint to make room for new functionality. The main benefits of componentization include performance, reliability, customization, licensing and security.
Containerization and Cloud Computing for Agility
TechTarget explains how applications that require agility and resiliency should split between cloud services for front end development and container development for the back end. Container development in the back end needs to be able to current IT operations in order to successfully deploy.
Containerization for Security
If security and compliance are your main motivators for modernization, then containerization is your best approach. TechTarget describes containerization as a way to deploy distributed application on an operating system (OS) level without launching an entire new virtual machine for each individual app.
CIO identifies the primary benefit of containerization is getting software to run reliably when moving from one computing environment to another. Each container operates independently and requires little resources from the host server. Containerization promotes security due to isolation of apps in smaller groups. Vulnerabilities only affect a small portion of apps versus an entire system as they are shielded in containers.
