Application Modernization

Looking for a reliable partner who knows both application development and data platform migration? We have the people, process, and products to help you move to the cloud or migrate to new platforms.

Typical application modernization challenges that we see

The core offerings of our business are application development and modernization, as well as post-deployment support. We know that all applications have to be connected to databases so, they need to be addressed holistically. Very often, the application modernization effort triggers a necessity to modernize a legacy database platform. As we help bring these outdated applications into the modern world with proven solutions meant to optimize and make ongoing management easier for the future.

We have a solid understanding of the common challenges you are likely to face while implementing such projects. Whether it comes down to targeting a single application, a family of apps, or a full portfolio, we have seen it all and can choose the right path based on our experience. Discover the most typical challenges that we faced over the last 18 years in application modernization projects below.

Challenge

Solution

Moving the application to the cloud

We know all the ‘gotchas’ and all the issues that may occur while moving your applications to any modern cloud database platform. Also, we can help you discover the right path to building the new architecture for your application running in the cloud. We can craft the new system, using specific web services for that particular cloud platform.

Rewriting the application to optimize it for the new database platform

It is often more cost-effective to rewrite the application to gain the performance and flexibility that you require. ABCloudZ has deep knowledge of all major development tools and frameworks, from mobile apps and websites to internal purpose-built cloud solutions, we can easily find the most effective application modernization solution to take full advantage of the new platform.

Converting embedded SQL statements

Your applications interact with databases, which are also a subject of modernization. We have a proven approach to this step.

First, we extract all the SQL statements from the source application code using our in-house automated tools. Then, we convert these extracted statements to make them compatible with the new database platform. We may opt for leveraging automated conversion tools, such as SQL Server Migration Assistant, AWS Schema Conversion Tool, and our internal tools. In rare cases, we rely on our experience to perform the manual conversion. Then, we apply the converted code to the source application files and compile the project, building the new application.

SQL code unification

Chances are the customer may need to support both old and new database systems for a certain period of time. In that case, we need to unify the SQL code in such a way that it can be interpreted by two database engines. To do so, we analyze the extracted SQL code and classify the code into one of the categories below:

  1. Doesn’t require modification and can be executed against both database platforms without conversion
  2. Requires unification to be used with both databases afterward (for example, we can use ANSI SQL standard)
  3. Can be automatically converted using specific conversion tools
  4. Requires manual conversion and should be duplicated in the application

In the end, you can run the application against both old and new database platforms.

Getting started offers

In most of the application modernization projects we start from the database, but very quickly get to application re-platforming or upgrade topics. At the end of the day, the customers want to see their applications running on the new database platform.

During the database migration project, you need to convert all the database objects. At the application level, you need to adjust application code, interfaces and sometimes completely rewrite the business logic.

Usually, application modernization requires a lot of manual work, there’s no easy way to convert applications using a single click.

We have a variety of offers to help you get the most out of your application running on your new database platform, making it compatible with all the latest features of modern on-premises or cloud platforms.

How we unified application to support SQL Server and Sybase

A financial service software provider needed to upgrade their customer-facing applications to SQL Server while keeping their Sybase ASE database. Our Sybase SQL Server Application Unification process allowed them to use SQL Server as a new database engine.

We came up with a way to create an identical version of their existing Sybase ASE database running in SQL Server environment and performed some code unification that allowed the Power Builder application front end to interact with both databases. Thus, the customer’s system now meets the rigorous high availability and encryption industry standards.

Benefits

The modern market demands force customers to upgrade from old database environments, but very often they need to keep the original system running as well.

Using SQL Server allowed our client to meet regulations that required high availability features such as Always-On along with Transparent Data Encryption to secure their financial data.

The following video shows how we used this innovative Sybase SQL Server application unification approach to meet our customers’ requirements.
