scalability through virtualization, they may not scale as rapidly or
efficiently as containerized environments.
Who is it best
for? Businesses with diverse workloads requiring different operating
systems or legacy applications. VMs are also suitable for scenarios where
strong isolation between applications is paramount, such as in multi-tenant
environments.
5. Serverless Computing: Embracing Event-Driven Architectures
In the realm of
cloud alternatives, serverless computing stands out as a paradigm shift
in application development. With serverless platforms, developers can focus on
writing code without worrying about server management or provisioning.
