Cloud Computing & Migration

What is Cloud Computing & Migration?

Cloud Computing & Migration refers to the broad category of software, services, and strategies involved in leveraging cloud-based infrastructure and moving existing IT assets (applications, data, infrastructure) from on-premises environments or other cloud platforms to a new cloud environment. This encompasses everything from the core cloud infrastructure providers (hyperscalers like AWS, Azure, GCP) to specialized tools and services that facilitate the migration process, optimize cloud operations, ensure security, and manage costs. The goal is to gain benefits such as scalability, flexibility, cost efficiency, improved performance, and enhanced disaster recovery capabilities offered by cloud platforms.

Key Considerations When Evaluating Solutions

When evaluating Cloud Computing & Migration solutions, buyers should critically assess several factors to ensure alignment with their business objectives and technical requirements.
