What is a platform as a service?
Platform as a service is a cloud computing model that enables
customers to build, test, run, and deploy applications while
avoiding the need to maintain infrastructure. PaaS vendors offer a
cloud platform—involving servers, development tools, databases,
networking, middleware, etc.—to manage the product lifecycle.
Basically, PaaS has three components:
Cloud-based infrastructure comprises data
storage, virtual machines, firewalls, virtualization, and
Development tools for creating and managing apps.
A graphic user interface (GUI) that allows
software engineers and
to perform the
necessary tasks. As the GUI is available online, software experts
can sign in via their tech devices and collaborate remotely.
The types of the platform as a service:
Public. PaaS software runs on the public cloud,
which means that numerous organizations employ the same platform
simultaneously. In fact, a public PaaS delivers infinite
Private. Companies use an isolated, private
segment of the cloud, which is not available for third parties. In
this case, a firm utilizes its own infrastructure and servers,
which contributes to increased security.
Hybrid. In this case, enterprises have the
flexibility to choose which resources (i.e., apps, data) can be
accessed via a public cloud and which are stored in a private
cloud. Therefore, it is possible to move resources between the two
clouds depending on business needs.
A private PaaS is the safest option that allows businesses to
prevent technical risks and potential vulnerabilities. Organizations
that operate with sensitive data and have to ensure compliance with
security regulations (GDPR, HIPAA, etc.) should use a private PaaS
model. Examples of such companies are providers of banking,
financial, and healthcare services.
Pricing of a PaaS model
The idea behind the PaaS pricing is to charge customers for the
resources they actually utilize, which is called the pay-as-you-go
model. PaaS providers may also require a fixed fee for using a
specified amount of resources.
The key advantages of the platform as a service
There are many benefits of PaaS:
Improved time to market. Using PaaS, software
engineers are not responsible for creating, configuring, and
provisioning their own app development platforms and back-end
infrastructure. Software experts only need to build and test
software solutions. PaaS vendors, in their turn, perform tasks
such as ongoing system support, resource allocation, and
Lower costs. Enterprises are charged only for the
resources they use. Hence, clients do not have to pay excessively
for idle resources during periods of low traffic.
Scalability. The scaling of on-premises software
is expensive and resource-consuming. To handle heavy loads,
businesses have to purchase additional computational and storage
capacity. A PaaS model offers cost-effective scalability
on-demand. With PaaS, companies can easily enable autoscaling of
resources and load balancing. Find out
why it is important to ensure scalability.
Ease of licensing. Platform as a service
providers acquire licenses for development tools, operating
systems, and other components for managing the application
Increased flexibility. PaaS vendors offer a
shared software development environment that enables software
engineers and DevOps experts to collaborate on projects remotely
and use various programming tools available out of the box.
PaaS is often used in building microservices and serverless
architectures that allow for achieving scalability, high
availability, fault tolerance, and performance.
Examples of trusted PaaS vendors: Amazon Web
Services (AWS), Microsoft Azure, and Google Cloud Platform.
