What is Cloud Computing?

Cloud computing is a technology that allows users to access computing resources over the internet instead of having to maintain and manage their own on-premises infrastructure. When discussing cloud computing advantages and disadvantages, you’ll find PaaS as the preferred solution to deliver various services, such as servers, storage, databases, and software applications, which can be scaled up or down according to the user’s needs. Cloud computing has become increasingly popular due to its flexibility, cost-effectiveness, and scalability.

One of the models of cloud computing is Platform as a Service (PaaS). PaaS is a cloud computing service that provides users with a platform for developing, running, and managing applications without worrying about the underlying infrastructure. Instead, PaaS vendors offer a pre-built platform with the hardware, operating system, database, and middleware components required to develop and deploy applications.

PaaS allows developers to focus on creating and improving applications without worrying about the underlying infrastructure. It provides a consistent and standardized environment that can be easily customized to suit the application’s needs. With PaaS, developers can quickly develop, test, and deploy applications, reducing the time to market.

PaaS also provides automatic scaling capabilities that allow applications to scale up or down dynamically, depending on the demand. This ensures that the application can handle sudden spikes in traffic without any performance issues.

In the context of what is cloud computing, PaaS is a cloud computing service that provides developers with a platform for developing, testing, and deploying applications without worrying about the underlying infrastructure. In addition, it offers automatic scaling capabilities, a consistent and standardized environment, and reduced time-to-market, making it an attractive option for many organizations.

How Does PaaS Work?

PaaS mainly deals with application and product development. Unlike other cloud computing services delivery models such as IaaS or SaaS, it’s better suited for development workflows.

A typical PaaS product is a combination of the following three components:

  1. Cloud Infrastructure comprises the OS, virtual machines, networking, storage, and firewalls. This is the technological base for your system that ensures a secure, networked computing environment for development.
  2. Software is the collective name for the tools required for creation, deployment, and maintenance. This is a customizable layer that supports development workflows by providing scaffolding, templating, and debugging components. This layer is often scalable, secure, and future-proof.
  3. GUI is often the top-most layer that allows users to view various functions and interact with the PaaS platform. It’s where the development teams perform their tasks.

Leading PaaS service providers allow users to customize these layers so that they can come up with the right set of tools and components for their projects. As a result, developers can collaborate in major development stages such as product development, testing, and implementation.

Types of PaaS

PaaS in cloud computing comes in several flavors to accommodate the various software development processes and operations. The following are the six popular types of PaaS available in the market. :

Public PaaS

Public PaaS vendors offer middleware that allows developers to create, configure, and manage servers and databases. In this model the vendor operates infrastructural elements such as OS and computing engines. Users often can’t change or replace these components.

In some public PaaS setups, multiple accounts share the underlying infrastructure resources. However, better standalone instances are offered at higher priced tiers.

Private PaaS

Private PaaS can be deployed on any infrastructure (generally on a cluster of dedicated servers) managed by the company’s IT teams. As a result, private PaaS offers better safety and compliance, allowing users to create, deploy, test, and maintain their apps and adhere to the company’s security and privacy guidelines.

In a private PaaS setup, an enterprise opts for a partially or fully segregated portion of its cloud infrastructure instead of sharing resources accessible to everyone in a public cloud.

Hybrid PaaS

Hybrid PaaS is a blend of public and private PaaS. Companies can deploy the cloud publicly or privately based on the level of security and access they require for specific projects.

Hybrid PaaS uses a hybrid cloud to communicate between the public and private segments.

Communication PaaS

Communication PaaS lets developers include real-time communication capabilities like messaging, voice, and video in their apps without requiring a separate communications infrastructure. It contains pre-built libraries, APIs, and sample code developers can integrate into their apps.

Mobile PaaS

Mobile PaaS delivers backend capabilities required to create, deploy and manage high-quality and stable mobile applications. These platforms support software development kits (SDK) for all popular mobile platforms such as Android and iOS.

Open PaaS

Open-source PaaS gives users more control over where and how they build and host applications. It still requires a system to manage servers, but it reduces the time and effort required to configure and launch development environments.

Pros and Cons of PaaS

Like all technologies, PaaS comes with advantages and disadvantages. Here’s a rundown of these pointers.

Advantages of PaaS Technology

PaaS is suitable for businesses and startups of all sizes. It’s cost-effective, allowing businesses to launch their products to the market faster with less expenses than dedicated servers in-house platforms.

Companies with remote workers can accelerate software development by focusing on what they specialize in without worrying about maintaining public or hybrid PaaS in cloud computing infrastructure. As such, PaaS is a great option for businesses looking for virtualization in cloud computing.

Other key advantages of PaaS in cloud computing include:

  • Speed to Market: PaaS allows developers and businesses to create, test and launch applications fast and easily.
  • Scalability: PaaS platforms are flexible, allowing you to increase capacity and resources to meet the project’s requirements.
  • Few Restrictions: Popular PaaS platforms place little to no restrictions on how applications can be developed or deployed.
  • Ease of Use: Most operational tools are pre-installed by PaaS vendors to ensure faster and hassle-free development solutions.
  • Control: The ability to update an application without interruptions for customers.
  • Remote Collaboration: These days, development is done by remote distributed teams. PaaS is ideal for collaborative development by globally distributed teams that need a seamless development environment for the project.

Challenges in Adopting PaaS Technology

While developing and launching apps using PaaS platforms is easy, the actual capabilities heavily depend on the PaaS vendor’s capabilities. For instance, if a PaaS in cloud computing service provider doesn’t support a programming language, you cannot build and launch apps using that language on the platform. An important outcome of this challenge is that you can use PaaS features and adoption rate as an indication of trends in dedicated servers and cloud computing.

Other challenges you might face include:

  • Vendor lock-in: Switching cloud vendors or moving data to a different platform is difficult and costly in terms of time and money.
  • Lack of Prefered Technologies: PaaS platforms, particularly public PaaS, often don’t support unpopular technologies. As such, you need to find out the supported technologies before signing on for the platform.
  • Security Risks: While PaaS platforms are secure by default, you should always assume otherwise and build security into your workflow and development SOPs.

  5. Agile development and DevOps: PaaS platforms embrace the entire DevOps release cycle, making it flexible and automated.

How is Platform as a Service different from Serverless Computing?

PaaS and Serverless computing platforms help ensure developers spend more time writing code rather than worrying about the infrastructure on which it runs.

However, there are key differences between PaaS and Serverless:

  • Scaling Resources: In Serverless cloud computing, scaling is automated and usually instant, without requiring additional configuration or vendor intervention. On the other hand, scaling PaaS resources is manual and requires users to perform specific forecasting for accurate on-demand scaling.
  • Pricing: Serverless cloud computing can be cost-effective, especially for small workloads, since developers need to only pay for the services they consume. PaaS pricing varies, based on the packages offered by your cloud provider..
  • Application Spin-up: Serverless computing model is event-driven. When a function is invoked, the provider runs a server and shuts it later so that the resources can be employed elsewhere. PaaS solutions continually utilize resources and often require manual shut-down.
  • Control: PaaS offers developers control over everything, including the development environment and the infrastructure. Serverless cloud computing offers less control since developers are restricted to just the code they write only.
