We’ve all at least once came across platform as a service (PaaS) in our lives, where developers mainly rely on cloud providers’ development tools to build you the applications you use (like your windows).

But, have you ever wondered what happens behind the scenes?

PaaS explained

PaaS is one of the main three cloud computing models, as it makes web application development simpler than ever on all sides, starting with the developers themselves up to the whole backend management.

Platform as a service allows you to manage applications without needing to build the infrastructure from scratch, or any other software development process for that matter.

Being a deployment environment in the cloud, PaaS enjoys all the resources that you need to deliver simple or even sophisticated cloud-based apps. These resources are what you end up purchasing from a cloud service provider to build your own applications.

Ultimately, PaaS is there to carry on the complete lifecycle of applications, which includes building, testing, deploying, managing, and updating.

All while granting you the ability to avoid unnecessary complexity/expenses of software licenses, making your cloud provider responsible for everything else.

(The other two main cloud computing models are the IaaS and the SaaS)

PaaS types

Various types of PaaS include:

• Public PaaS
• Private PaaS
• Hybrid PaaS

Here's a deeper look at each type, including its most suitable deployment environment:

Public PaaS

Public PaaS is the best fit for the public cloud, allowing you to control software deployment while the cloud provider manages the other IT components delivery that’s necessary to host the databases and applications.

Most suitable for small and medium-sized companies, public PaaS vendors offer middleware that enables you to configure and control servers. Therefore, PaaS runs together with the Infrastructure as a service (IaaS) and the public cloud.

Private PaaS

Working within the company’s private cloud, the private PaaS delivers security, low costs, and the agility of the public PaaS.

Additionally, Private PaaS helps with maintaining the internal resources usage, and helps developers with deploying their private company applications with minimum-cost.

Hybrid PaaS

With a combination of the public PaaS and the private PaaS, companies get the public PaaS infinite capacity and the security/cost-effectiveness of the private PaaS. Which, by default, is applicable with the hybrid cloud.

PaaS use cases

Mainly valid to ease application development and deployment, there are in fact other use cases on why enterprises use PaaS, such as the following:

Means of communications

PaaS serves as a delivery mechanism for communications platforms, which allows developers to add communications features to applications, such as voice or video communication.

Accurate business analytics

PaaS tools provide enterprises with accurate data analysis that helps businesses to grasp better behavior insights on how to make better decisions regarding future demands.

Smooth API development

Managing, running, and securing application programming interfaces never got easier. Whether it’s the creation of new APIs or new interfaces for existing APIs, PaaS provides you with the right tools to do it effortlessly.

PaaS Advantages

It’s true that PaaS offers the same advantages as IaaS, but it comes with additional features and other business tools. Some well-known PaaS advantages include:

Efficient application lifecycle

With all the application lifecycle capabilities available, PaaS gives it all without the need for additional required skills, cutting the time it takes to code, and nurtures an inspiring environment.

The apps available for the web application lifecycle include the building, testing, deploying, managing, and updating phases.

Easily develop multiple platforms

With more development options provided for you by the service providers, you get to experience easy yet exceptional ways to develop different platforms, including mobile devices and computers.

Affordable advanced tools

You get to use advanced software, business, and analytics tools that you couldn’t straightforward purchase, opening infinite possibilities for your organizations with a pay-as-you-go model.

PaaS vendors

It’s hard to consider the nuances with so many PaaS providers, such as the service availability or the languages supported. That’s why it’s very recommended to test first and see if the provider services meet your needs.

Examples of PaaS vendors & products include but not limited to:

• AWS Elastic Beanstalk

Allows you to create and deploy web services with languages like Java and PHP on common servers like Passenger and Apache.

• Google App Engine

Supports distributed web applications using PHP, Java, and Python.

PaaS next

No matter which PaaS provider you choose, make sure to keep your company’s data secured as your first priority

With different types to support all your web development and application needs depending on your cloud deployment and business size.

PaaS can offer you accurate analytics, smooth development, and effortless API management, among other exclusive advantages that are not found anywhere else.

Hybrid cloud, cloud hybrid, or multi-cloud. No matter which definition of hybrid cloud you use, the great benefits are the same!

With superior security, automated data redundancy, high availability, and disaster recovery. Hybrid cloud is the ultimate choice for small and big businesses alike.

Imagine a hybrid train feeding on solar and electric power, 2 distinguished technologies functioning differently.

When both are combined appropriately, it results in a more powerful train than a solar or electric-only train, enhancing advantages and overcoming disadvantages of each power.

Hybrid clouds maintain the same approach, unifying public and private cloud services to create a single and cost-optimal IT infrastructure.

Hybrid cloud: what connects the separate clouds

Public clouds, private clouds, and on-premises infrastructure can connect through:

• Application Programming Interfaces (APIs)
• Virtual Private Networks (VPNs)
• Wide Area Networks (WANs)
• Local area networks (LANs)

Hybrid cloud: types of environments

• Public cloud: shared by multiple organizations, it runs by an external vendor that may include servers in one or more data centers

• Private cloud: wholly dedicated to one company, all the files are not shared, maintained, and secured by the organizations-themselves

• On-premises (legacy): where deployments don’t use cloud technology. Instead, organizations use the traditional practice of purchasing software licenses.

Any combination of the above cloud types can be considered “hybrid cloud”

Hybrid cloud: How does it work?

Hybrid clouds focus on transforming portions of a company’s on-premises data center into private cloud infrastructure, then connecting that infrastructure to public cloud environments hosted off-premises by a public cloud provider.

This happens using unified management tools or advanced enterprise middleware to combine cloud resources across the environments.

Hybrid cloud: the advantages within

Offering many competitive edges, the benefits of a hybrid cloud include:

• Improved productivity: agility is on top when it comes to hybrid clouds, helping you expand effortlessly and deploy to all clouds.

• Exceptional security: keep sensitive data on-premises in a secure private cloud while running the rest of your applications using a public cloud.

• Potential acceleration: avoid service interruptions due to cloud crashes by relying on the other cloud. Also, gain faster integration and combination with partners or third parties to deliver new products and services.

• Cost control: run every application as efficiently as possible by adding cloud resources -only when- needed to accommodate the peak periods.

Hybrid cloud: the evil drawbacks

Because nothing’s perfect without the imperfections, some of the top hybrid cloud disadvantages are:

• Complexity all over: setting up a hybrid cloud takes more steps than deploying a single cloud, as hybrid clouds consist of at least 1 private cloud and 1 public cloud, or 2 and more clouds from each.

• Tough to secure: requiring multiple security products at times for the company’s public cloud, as it’s only the private cloud that runs behind its firewall.

• Barbed mixture: not all private and public clouds are fully compatible, resulting in slow responses for hybrid cloud applications. Additionally, the cost may significantly increase in data misplacement, inevitably calling for a unique set of outstanding technical skills.

Hybrid cloud: use cases and scenarios

• Disaster recovery: by backing up data in the cloud carefully to avoid bandwidth consumption.

• Cloud provider adventure: where a group of skilled people explore the cloud tools and learn how to deal with them before adopting a public cloud approach.

• Future flexibility: hybrid clouds match your exact data requirements to the public/private cloud resources that are guaranteed to handle them the best.

Hybrid cloud: best of both worlds

The presence of multiple environments can be a powerful defense against security risks and maintain the tools freely for complete scaling, saving, and maximum efficiency.

If the road is clear, then why limit your options? Go on and consider all the way hybrid cloud now! Get all the agility you need for the next level, and grasp the best of both worlds.

Next: Everything as a service: Beginner's guide to XaaS

What is an API? It's a question everyone asks! Okay… not really, but we're glad you did!
Let's say hello to the golden buzzer within the tech industry today.

API is a software intermediary between you and your apps or between apps.

All API acts use your phone to send a message or check the weather.

Think of the waiter in a restaurant who takes your order, gets your food, and your bill right after. This waiter's the restaurant's API, sparing you the work behind the scenes.

API could also:

• Simplify app development
• Save time and money
• Give you flexibility
• Provide administration to expand your brand.

Here are 5 reasons you must have a good API.

1- Assemble your foundation using an API

The best API advantages flourish when you build your initial blocks.

For instance, if your business involves food delivery.

You can use a phone's geolocation API to locate the riders, one API to communicate messages to them, and another API to handle payments.

APIs are all about connecting the trim pieces to form the bigger picture. They allow you to use data quickly and efficiently when looking to do something specific with the information.

2- Upsell & add SaaS value with an API

APIs integrate well with SaaS products, as they're built on a distributed model. Large corporate clients notice this and tend to want better adjustments into their workflows using the API!

While CRM vendors like Zoho offer accessible backend API data to their clients to adjust freely, Global CRM SaaS providers like Salesforce provide this data for higher-end subscribers only.

The possibilities are endless, as others may offer full API access to tempt users as an additional part of a monthly subscription or a specific package with a different price.

3- APIs Automate everything

Computers can manage work with APIs without human interactions.

You can quickly update workflows through APIs, make the information delivery more flexible, access the app components, or automatically publish content the way you like.

4- Go API and gain more traffic

You should consider launching APIs if you run your own businesses

That'll help you reach new target audiences across online platforms and have the potential to:

• Extend your customer-reach
• Support your marketing activities
• Increase your revenue
• Ease integration of backend data

5- APIs and innovators, simpler than ever

There's no need to be a technology expert to profit from building a platform.

By saving time and engineering hours that would have been required to build a platform, APIs allow you a new experience while utilizing what is already adopted.

All happens via repackaging API data, from which you can simply build the products.

Final thoughts

API can come in different policies like private for you, partner with a business, or public for all users. It could also, as we mentioned, simplify app development, save time and money, give you flexibility and administration to expand your brand.

Fusing an API in your product is a game-changer and can bring a competitive edge.

Also, don't forget that an API comes equipped with maintenance, which ultimately makes them cheaper in the long run.

Overall, APIs can take care of many functions of your company, which gives you enough time and space to focus on and improve what your company does best.
