As more enterprise solutions and services move into the cloud, businesses are beginning to wonder how much of their data should be migrated. Workloads and technology continue to evolve, and business decisions have been made according to best practices at that time. What we end up with is a mixture of applications, some on-prem legacy apps and some cloud-based apps. This combination can create problems and inefficiencies as it is not as easily scalable from both a consumption and resource perspective as a fully cloud-based environment.
Migration is by no means an easy task — it takes time, resources and pre-planning to do it right. Some businesses choose to continue operating in that complicated and outdated environment; however, those that choose to invest in the cloud by moving to a PaaS (Platform as a Service) configuration see many immediate benefits.
Top 5 Benefits of a PaaS configuration
- Security - Cloud providers that want to stay competitive must keep up with constant changes in security standards. This means that updates and patches are automatically pushed out and your data is always protected by the most current version.
- Cost Savings - With data now stored in the cloud, costly servers, and the dedicated resources it takes to manage them, are no longer a requirement. Also, most cloud apps are priced on a pay-as-you-go model, and PaaS structures are typically charged by the amount of memory consumed per hour. This means that you never pay for more than you consume.
- Scalability - Businesses always need to be prepared for unexpected growth, and as a result, IT would need to keep a “reserve” setup ready to go. Most of the time, between the unused licenses and idle capacity, this only resulted in a waste of resources. Cloud services are instantly scalable and can meet your needs in a matter of minutes.
- Collaboration and Mobility - A PaaS model means that your environment has been built from the ground up to be mobile friendly and accessible from any authenticated device. All of your data is housed in one centralized location that can be accessed safely and securely from anywhere outside of your network.
- App Enhancement - Since cloud services are built to enhance your applications, businesses are free to choose specialized apps that best suit each of their needs, then go in, and connect the dots. Rather than choosing one platform and then having to make it work for every function, they can tailor each piece and then make them work together efficiently.
How to make the move
Once the decision is made to migrate, most IT departments are eager to get the job done and start reaping the rewards. It is important, however, to follow best practices to ensure a smooth transition:
- First, take the time beforehand to “de-clutter” your legacy apps, just as you would clean out your closets and cupboards before moving to a new house. Without proper attention, any inefficiencies or bloating that exist on-prem will continue to exist in the cloud.
- Second, make sure that your legacy app will be able to function in the cloud. Does your cloud provider support your current platform framework?
- Finally, keep in mind that legacy applications were created to run on a single server and they will now need to adapt to the cloud’s clustering scenario.
Understandably, it can seem like a daunting task to migrate your application to a new platform. Moving from a legacy system to a modern cloud environment is a big investment. It requires up-front work to re-architect your app to run on the cloud. Many businesses get so overwhelmed by the thought that they continue to operate with outdated systems. Most, however, can see that the long-term benefits of enhancing their application to be adaptable and scalable far outweigh any temporary discomfort.
