In a monolithic architecture, all components of the application are packaged together as a
single unit. While this can simplify deployment, it may lead to challenges in scaling and
maintaining large applications.
Microservices Architecture
Microservices architecture breaks the application into smaller, independent services that
can be developed and deployed individually. This approach enhances flexibility and
scalability, allowing teams to work concurrently.
Serverless Architecture
Serverless architecture allows developers to build applications without managing server
infrastructure. This model enables automatic scaling and reduces operational costs,
making it a popular choice for modern applications.

internet rather than on local servers. This model provides flexibility, scalability, and cost
savings.
Types of Cloud Service Models
Infrastructure as a Service (IaaS)
IaaS provides virtualized computing resources over the internet. Users can manage
operating systems, storage, and applications while the service provider handles the
underlying infrastructure.
Platform as a Service (PaaS)
PaaS offers a platform allowing developers to build, test, and deploy applications without
managing the underlying infrastructure. It simplifies the development process and
accelerates time-to-market.
Software as a Service (SaaS)
SaaS delivers software applications via the internet on a subscription basis. Users can
access software from any device with an internet connection, eliminating the need for
installation and maintenance.
