You want your legacy IT infrastructure to run cross clouds. But your legacy-defined architecture has become incredibly complex and you are facing unneccessary costs and disruptions while moving workloads to cloud. Somewhere along the line, your cloud first intentions might fade in the face of expediency and haphazard technology adoption. You need to reengineer the legacy architecture from the ground to keep the technology strategy humming.
But how do you know the areas where your IT architecture is in a slump. Here are 5 key warning signs that your legacy IT architecture won’t support your cloud initiatives.
Manual Re-keying: With manual rekeying it is impossible to track IT problems and they continue over and again. It is not feasible to cross manage inconsistencies, maintenance issues, and change requests with this approach. Managing a change request will require the IT teams to embed new code and replace the previous ones. Automation can prevent such problems from expanding. Business users can alter business rules reduce the impact of change. Ultimately, this will make the IT architecture flexible and sustainable to modernization initiatives.
Point to Point Connectivity: This is a mission critical concern for companies working with large number of business partners. Point to point connectivity model is not ideal for entities which have a larger set of integration requirements. It should be referred when the end points to connect applications are fairly small. Businesses should embrace Any-to-Any connectivity that allows users to subscribe system like topics as many times as they desire. This helps businesses in reaching the revenue time faster.
Obsolete Systems: One of the biggest roadblocks to any change management initiative. Imagine that you have built a home grown solution on Visual Basic that Microsoft is not supporting since decades. And even SQL server doesn’t support it for reading and writing anything. There is no point of spilling money for purchasing those software licenses which don't deliver new functionalities. Ultimately, you might end up squandering huge amount of resources in maintaining those systems.
Lack of Integration: A highly fragmented IT architecture can impede the deliverables. Teams use different systems for accomplishing different business objectives. During this process and cycle runs, teams set up multiple versions of truth while updating data into different systems. They generate a complex web of hairball where coding one thing changes the behavior of another thing. Teams can achieve greater agility and interoperability between business systems if the underlying technologies are integrated in a standard manner.
No Centralized Architecture: Teams without a centralized interface spend too much time in extending the logic to other modules and systems. One single view is required to manage the rapid proliferation of business technologies. A centralized interface helps teams in tackling the burgeoning computational needs and accommodating new changes. Teams can avoid frequent checkouts/check-ins in developed codes, drive collaboration across the IT environment and tap new opportunities.
