Modernize and Migrate Applications to GCP

The Google Cloud Platform provides the technology and services that make running mainframe applications in the cloud a safe, secure, reliable way to achieve high performance results and fuel future innovation for the organization.  

There are specific elements of the Google Cloud Platform that are relevant to a mainframe migration project. Here are some of them:

  • The Google Cloud Platform provides a broad set of infrastructure services, such as computing power, storage options, networking and databases that are delivered as a utility: on-demand, available in seconds, with pay-as-you-go pricing. From data warehousing to deployment tools, directories to content delivery, several Google Cloud Platform services are available.
  • New services can be provisioned quickly, without upfront capital expense. This allows enterprises, start-ups, small and medium-sized businesses, and customers in the public sector to access the building blocks they need to respond quickly to changing business requirements.
  • The Google Cloud Platform serves millions of active customers in more than 190 countries. Google is steadily expanding global infrastructure to help our customers achieve shorter latency times and higher throughput, to ensure that their data resides only in the region they specify. As customers grow their businesses, Google Cloud Platform will continue to provide infrastructure that meets their global requirements.

Three Strong Promises

Functional Equivalence

The migrated application’s behavior is identical to that of the original one.

Performance Equivalence

The migrated application will perform at least as well as the original one.

Maintenance Equivalence

The maintenance of the migrated application will be comparable in effort to the original application.

The Google Cloud Platform Environment

The Virtual Private Cloud (VPC) lets you provision a logically isolated section of the Google Cloud Platform where you launch and manage Google Cloud resources in a virtual network that you define. It’s your private area within the Google  Cloud Platform.

Computing Resources

GCP provides secure, resizable compute capacity in the Google Cloud. It serves as the foundation upon which your application sits.  


GCP offers a reliable service for storage, backup and archiving of all types of data. They are combined to meet the storage requirements of your IT infrastructure.


Google’s Cloud SQL Relational Database Service is where all your legacy relational data will reside.  This includes any flat file data that has been converted to relational.

Load Balancing

GCP automatically distributes incoming application traffic across multiple instances to achieve scalability, high-performance, and fault tolerance in your migrated applications.


In the Google Cloud environment, you will use the Lightweight Directory Access Protocol (LDAP) for accessing and maintaining distributed directory information services.

Source Control

GCP uses a fully managed source control service providing secure and private GIT repositories. This eliminates the need to operate your own source control system, or worry about scaling its infrastructure.
