PaaS Assessment: A Easier Way to Build Software Applications
Platform as a Service (PaaS) is software that enables third-party service providers to provide platforms to their customers and to develop, run and manage software applications without having to build and maintain themselves. the underlying infrastructure. It is an engine of development.
Most Platforms as a Service include templates or build packs. notice How to create a particular type of application usually focuses on the most popular. 12-element methodology. This is why PaaS options are often labeled as “opinion” and are ideal for new, entirely new applications.
Emergence of Cloud Computing Companies such as Amazon Web Services, Microsoft, and Google have assembled the key components needed to launch an application on their own platform, with a single command or mouse click on code.
This simplification makes software development faster and easier and hides the underlying compute, storage, database, operating system, and network resources needed to run applications, thereby increasing the scope of work. from the developer. It will be reduced. PaaS providers charge for the use of these resources, and in some cases the use of the platform itself, based on the number of applications per user (or “seat”) or hosted.
What makes PaaS
Like other cloud services such as infrastructure as a service (IaaS) and software as a service (SaaS), PaaS is typically accessed over the internet, but can also be deployed on-premises or in hybrid mode. In all cases, the underlying infrastructure on which the application runs is managed by the service provider. In many cases, customers can decide where to physically host their applications and choose the performance or security of their environment. There are often additional charges.
The components of a typical PaaS are:
- Management infrastructure: Vendors manage the servers, storage, data centers, and network resources needed to run applications.
- Design, test, and development tools: The integrated development environment brings together the tools you need to build your software, including source code editors, compilers, and debuggers. Some vendors also include collaboration tools that allow developers to share and contribute to each other’s work.
- Middleware: PaaS often contains the necessary tools to integrate user applications with different operating systems.
- Operating System and Database: PaaS provides an operating system to run applications and a variety of managed database options.
PaaS and IaaS
For many, the PaaS and IaaS debate is market-driven, but the decision to use the underlying building block itself (IaaS) or savvy PaaS is to seek speed. It is a decision that many people are making today. Application to the market.
As with any case of software development, this decision comes with trade-offs and depends on what your organization is trying to achieve.
Benefits of PaaS
One of the main benefits of using PaaS is the ability to quickly build and deploy applications. You don’t have to worry about setting up and maintaining the environment in which your application is running. This, in theory, allows developers to deploy faster and more consistently, allowing them to focus on differentiators rather than solving issues like infrastructure provisioning.
PaaS is maintained by the service provider and comes with service level agreements and other guarantees, so developers don’t have to worry about tedious and repetitive tasks like patching and patching. upgrade, ensuring the availability and stability of their environment. I can be sure it’s expensive. , Although the failure still occurs.
PaaS can also be a convenient gateway to new things Cloud native development method Program a language with no upfront investment to create a new environment
Most of the risks associated with using PaaS translate into a loss of control that professional developers must tolerate when relinquishing their applications to third-party vendors. These risks include information security and data resident issues, fear of vendor lockdown, and unplanned outages.
With PaaS, some team members may find it confusing because developers have a limited number of changes to make to their development environment. Failure to change the environment or deploy feature requirements by service providers can lead to business. Build your own internal development platform beyond PaaS.
So Benkepes wrote for Computerworld in 2017, PaaS is heavily embedded in container management and automation ideas, and major vendors such as cloud providers Red Hat, VMware, and Big Three are properly moving towards facilitating adoption of containers. Kubernetes in recent years.
It doesn’t mean PaaS is dead. Inevitably, PaaS has evolved as the industry has made a widespread migration to containerized applications coordinated by Kubernetes. There is always a market that simplifies software development, but the underlying platforms for making it evolve over time.
Some of the major PaaS providers include: Amazon Web Services (AWS), Google Cloud, Microsoft Azure, Red Hat, and Salesforce Heroku.
The Big Three cloud providers on AWS, Microsoft Azure, and Google Cloud have all made significant investments over the past decade to facilitate adoption of their services, integrating their own cloud components to facilitate adoption.
The main PaaS options still on the market include:
AWS Elastic Beanstalk
One of the first PaaS options, AWS Elastic Beanstalk, enables rapid deployment and management of cloud applications without having to learn about the underlying infrastructure. Elastic Beanstalk automatically manages the details of capacity provisioning, load balancing, scaling, and application health monitoring.
Cloud Foundry is an open source PaaS managed by the Cloud Foundry Foundation (CFF). Originally developed by VMware, it was transferred to Pivotal Software, a joint venture between EMC, VMware, and General Electric, and then to CFF in 2015. Like OpenShift, Cloud Foundry is designed to build and run applications based on containers. Kubernetes For orchestration.
Google App Engine
Google App Engine is a PaaS offering for developing and hosting web applications in data centers managed by Google. Applications are sandboxed, run, and automatically scaled across multiple servers.
Microsoft Azure Application Service
Microsoft Azure App Service is a fully managed PaaS that combines various Azure services on a single platform.
Red Hat OpenShift
Red Hat OpenShift is a family of PaaS offerings that you can host or deploy on-premises in the cloud to build and deploy containerized applications. The flagship product is the OpenShift Container Platform. It is an on-premises PaaS built on Red Hat Enterprise Linux and built around a Docker container orchestrated and managed by Kubernetes.
In the early days of popular PaaS, Heroku may have gone astray Since its acquisition by SaaS giant Salesforce in 2010, Heroku is part of a wide range of Salesforce platforms for developer tools, supporting a wide range of languages and thousands of developers running applications on them. I go. In fact, to use Heroku, you need to create a common runtime deployed in a virtualized Linux container. Dynos, As Heroku calls them, it is spread across the dyno grid on the AWS servers.
Evolution of PaaS
Platform as a service has become its own major category of cloud services, but containers (and the Managed Container-as-a-Service (CaaS) option developed by major vendors), serverless computing and The Function as a Service (FaaS) option offers many of the same benefits as PaaS, but for portability, flexibility and serverless computing, it promises an environment where you pay only for what you use .
