Frequently Asked Questions (FAQs)

What is Infrastructure as a Service (IaaS)?

IaaS provides access to fundamental computing resources, such as virtual machines, storage, and networks. With IaaS, you manage the operating system, applications, and data, while the provider manages the underlying infrastructure. AWS EC2 and Azure Virtual Machines are examples of IaaS.

What is Platform as a Service (PaaS)?

PaaS offers a platform for developing, running, and managing applications without the complexity of managing the underlying infrastructure. It provides tools and services for development, testing, and deployment. AWS Elastic Beanstalk and Azure App Service are examples of PaaS.

What is Software as a Service (SaaS)?

SaaS delivers software applications over the internet, typically on a subscription basis. Users access the software through a web browser or mobile app, and the provider manages the infrastructure, operating system, and application software. Examples include Salesforce, Google Workspace, and Microsoft 365.

How do AWS and Azure handle security?

Both AWS and Azure employ a layered security approach, including physical security, network security, and data security. They offer a wide range of security services, such as firewalls, intrusion detection systems, and data encryption. Both also maintain compliance with numerous industry standards and regulations.

What are Availability Zones?

Availability Zones are physically separate data centers within a region. They are designed to provide high availability and fault tolerance. AWS and Azure both utilize Availability Zones to protect against outages. Deploying applications across multiple Availability Zones ensures that if one zone fails, the application will continue to run in another zone.

What is cloud migration?

Cloud migration is the process of moving data, applications, and other business elements from on-premises data centers to the cloud, or from one cloud provider to another. There are various migration strategies, including lift-and-shift, re-platforming, and re-architecting.

What is serverless computing?

Serverless computing is a cloud computing execution model where the cloud provider dynamically manages the allocation of machine resources. Users only pay for the compute time they consume, without having to manage servers. AWS Lambda and Azure Functions are examples of serverless computing services.
