Don't let legacy systems hold you back

Don’t let legacy systems hold you back

If you remember the complexity, time and effort it involved to implement the system that your company currently uses , you’d probably be tempted to not change a thing. Especially if it is all still working fine, “if it ain’t broke, don’t fix it” right?

What if we tell you that the benefits by far outweigh the negatives?

While your legacy application may be working now, one cannot ignore the immense benefits of cloud adoption, especially the fact that it prepares for the day when your application no longer works.

As previously discussed, the cloud brings about many benefits, including:

  • Cost reduction – shifting large capex to lower predictable operating expenses
  • Utilisation of the latest technologies
  • Facilitation of seamless growth
  • More benefits detailed here

We understand how daunting it is to imagine reconfiguring everything, so we have identified some common legacy issues and put together the following, which explains how the cloud works to address these issues:

How do I know that the cloud is suitable for our business?

The cloud offers scalability, ubiquity and centricity, making it accessible for everyone. The key is to determine exactly where cloud can deliver the greatest value for your business, and devise a unique solution that best fits your situation. It may help to seek advice from a professional IT consulting firm who is experienced in assisting other businesses with cloud deployments.

Your cloud deployment can be performed in two ways:

  1. Keep your legacy business processes largely intact by re-hosting to a low-cost, updated environment
  2. Break your application into separate components with application re-architecture

Moving to the cloud takes advantage of the greater economies of scale that it provides, giving your business greater agility and resilience.

If we suddenly switch everything over how do we know it all works?

The great thing about the cloud is that you can adopt it gradually. Think of it as a process, and start by moving parts that would perform better and are easier to manage in the cloud. Once you are familiar with the environment you can begin to move other parts of the systems over. Cloud is relatively inexpensive to adopt and allows for quick deployment and testing, so your business is able to try it out for different parts of your system to determine what works best.

How do we know it’s safe?

Reliable cloud service providers are able to offer secure data centres with uptime guarantees. Moreover, the cloud offers security that cannot be achieved within your premises in the event of disasters, such as a fire or theft. By moving your applications and data offsite, cloud allows for disaster recovery and business continuity.

But we have so much stuff in our system!

Yes, legacy systems cannot just be removed overnight, however you can remap certain processes to start making use of the cloud.

For example, you can implement a cloud solution that pulls and processes data from your legacy system when required, providing results of an advanced IT system. Another use is utilising the cloud’s infinite processing power to analyse large volumes of  big data held within legacy systems, allowing businesses to promptly identify opportunities and react faster to changes in their market.

Our legacy application is what our staff are used to!

If you choose to deploy with a trusted managed cloud provider, they can assist in providing user training and familiarising your staff with the new systems to maximise the working relationship on all sides. Moreover, with the involvement of a professional software development team, your cloud applications can be custom designed to look and function exactly like your on-premise counterparts.

We don’t want to move the application outside its life cycle.

While this may be a legitimate reason to delay adoption, if you wait until the end of life for applications that may hang around for a decade, that is a decade’s worth of savings and productivity that your business is losing out on. Your competitors may already be moving to more efficient systems that allow them to be more agile in responding to market changes, giving them a competitive advantage over your business.

Cloud adoption allows for implementation of new agile practices that will keep your business from falling behind your competition. It is important that businesses start exploring the components of their business that are more suitable in the cloud, and eliminate the risk of being left behind with stale legacy systems.
