Understanding and classifying middleware applications is the most critical aspect and a complex task compared to the other Cloud adoption processes. In general, an organization holds multiple and diverse applications that are integrated within the system. A few of them include Off-the-shelf, legacy, and custom-built applications as well.
Whether you are planning to migrate your Migrate Custom Applications to the Cloud (OCI, AWS, GCP, or the other cloud platforms) or migrate middleware applications to Cloud, every legacy application will have its own set of migration requirements that are needed during the migration process. The goal is to migrate/move Oracle Middleware Applications to Cloud either with minimal or no effort.
Here are the 3 successful methods to migrate the custom Oracle Middleware Applications to the Cloud.
1. Re-Hosting – Lift & Shift Migration Approach
The first and foremost approach in migrating the middleware applications to the Oracle Cloud is that the applications that rely on the traditional compute/server applications or technologies based on their complexity will not benefit from re-factorizing the newer process technologies such as microservices or serverless ones.
For such applications, Suneratech recommends leveraging its Infrastructure as a Service (IaaS) offerings based on the specific cloud platform. By leveraging IaaS offerings, you can re-create servers/compute required to run the applications with a traditional data center. You can also choose from various cloud tools and concepts such as:
- On-demand self-service
- Broad network access
- Resource pooling
- Service integrations like API gateways Content Delivery Networks
We should also note that a big bug count of Oracle middleware applications potentially falls under this category. And many WebLogic off-the-shelf applications use the stateful sessions for clustering and require an additional effort to integrate with the newer cloud concepts like auto-scaling.
2. Re-Platform – Migrating the Applications to a Managed Cloud Platform
Here, we need to focus more on the applications to be moved to a managed cloud platform. The service availability to support the application deployment depends on the cloud provider that we have chosen. For example, AWS Cloud services support the custom application deployment that use different tech stack such as PHP, .Net, Java. Based on the business needs, you can Move Oracle Middleware Applications to Cloud such as Amazon Web Servies (AWS), Google Cloud Platform (GCP), or to other cloud platforms.
In these specific instances, the AWS Cloud takes over the Provisioning, Management, Autoscaling of the service/compute and network compliances. This significantly reduce the OpEx costs because the companies are no longer likely to maintain the resources such as Servers, Operating Systems, Networks, IT Team even after migrating to the Cloud platform.
3. Re-Architect – Recreating the existing Application for the Cloud
While most of the applications are migrated using Suneratech’s ‘Lift & Shift’ approach or via a managed platform, a few of the applications need to be entirely overhauled to ensure the correct functionality of the cloud. Also, re-architecting these types of applications allow the development team to ensure the concepts and tools utilize their full potential and gain the benefits of being deployed onto the cloud.
For instance, we can explore the opportunities in breaking down the monolithic applications into the smaller “Micro” services and can utilize serverless technologies such as Amazon Simple Queue Services (SQS) or Amazon Simple Notification Services (SNS) Lambdas, to improve the performance. During that specific time, you can also replace the traditional Oracle Relational Database Management Systems (RDBMS) with the newer concepts such as Object Storage, Data Lakes, or the NoSQL Databases.
Benefits of Migrating the Middleware Applications to the Cloud
Any organization has a portfolio of custom-built applications that supports a diverse range of Business Functions, ranging from the traditional back-office processes to the supply-chain, business-critical manufacturing, and customer-facing applications, where these have been customized to fit your needs and can leverage the Oracle DB to manage your business data. You can also move your Oracle solution to Oracle Cloud Infrastructure (OCI) to meet your business needs.
