The concepts of the cloud have been introduced in 2006. By 2018 the public clouds market share has made over $17 bln. – around 5% of the entire IT market. Let’s take a closer look at SaaS, PaaS and IaaS benefits enterprises can get with the cloud computing evolution.

Cloud computing is a better way to run your business. Instead of running your data yourself you use shared data centers. You just plug in like the utility. That’s fast to get started and costs less. It’s like Gmail compared to Microsoft. With Gmail, you need no servers and storage, no technical team. You don’t need to make upgrades. When you use any app that runs like a cloud you just log in, customize it, and start using it. That’s the power of cloud computing.

This power is changing the way we are thinking about software. Not just for consumer apps, clouds are used for business apps. That is called enterprise cloud computing. Businesses are running all kinds of apps in the clouds including custom-built apps that cost less than the traditional business apps. You don’t need to pay for other people and facilities to run them. And it turns out they are more scalable, more secure, and more reliable than the vast majority of apps. Here’s why:

  1. Multi-tenancy. With a multi-tenant app, there is a copy app for each business that is using it. It’s one app that everyone shares but it’s flexible enough for everyone to customize it to their specific needs.
  2. You don’t buy anything at all. Instead, you have all year up a predictable monthly subscription. You pay only for the functionalities you use.
  3. Cloud apps don’t eat up your valuable IT resources. You can focus on projects that really impact the business like deploying more apps.

Cloud computing is a simple idea but it has a huge impact on your bottom line.

IAAS, PAAS, SAAS Explained

IAAS is something you have to be thinking about once you started thinking about creating cloud architectures for your organization. When you start moving things up into the cloud you should know what IAAS is, how it works, how you are going to do it, what advantages of IAAS you can get. When it comes to clouds the main problem about it is that a lot of people talk about cloud as of one single big thing – the cloud. Most of people don’t really distinguish the components of the cloud. Here are the main components:

IAAS, PAAS, SAAS Explained

Types of Cloud Solution We Offer

SAAS (Software as a Service) is where you move your software up into the cloud. So no longer a software is actually installed onto your computer or tablet, the software is actually in the cloud. You just simply access it through something like a web browser. Instead, a software is installed on your computer, it is somewhere on a server.

IAAS (Infrastructure as a Service) is all about moving your infrastructure to the cloud. This is not the same as SAAS and not the same as a PAAS (platform as a service). All of these concepts are about moving the technology to the cloud but they revolve around different things. When we are talking about IAAS the first thing we should define is what infrastructure is. Basically, what we are doing is moving the server equipment up into the cloud and letting somebody else deal with their basic functioning. In the terms of infrastructure we are talking about an actual physical box that you had to buy but now, with hosted IP solutions you no longer have to buy that piece of infrastructure for your business. That can be hosted somewhere else. What else can you do with IAAS? Here’s the answer:

  • rent servers in the cloud;
  • buy any operating system as a service: a firewall, a telephone system, etc;
  • modify the configurations.

PAAS (Platform as a Service) is a cloud computing solution designed to help organizations and particular developers to run apps in the cloud.

IAAS Vs PAAS

So, what’s the difference between IAAS and PAAS? Traditional on-premise data centers, be it in-house or actual data center, you have to manage every aspect including purchasing and installing a hardware, the virtualization, and networking software, security staff, etc. Now and then you are responsible for maintaining the resources, fixing them when they fail, and replacing them as they age and become inefficient. When it comes to cloud offerings you get an alternative to the traditional on-premise data center. The major benefit of clouds is that you can choose how much or how little hardware to use and the price just according to that. If the server goes down a hosted company will take care of it.

To understand the differences among IAAS PAAS or SAAS, take a closer look at the table comparing these “as a service” technologies. The table demonstrates the services offered by Microsoft that is considered to be one of the top IAAS providers.

IAAS Vs PAAS

Here you see the difference in managing your applications: things what you manage and things that can be managed by a provider. In case of on-premises apps, you manage everything by yourself. That is why moving up into the cloud is considered an effective, cost and time-efficient way to streamline your business.

Cloud Application Development

Cloud applications can save huge upfront costs for organizations of any size. They are transforming the way how enterprise applications are built today.

When we are talking about cloud apps development we mean not only the process of development but also other services related to the cloud:

  • Migration from the legacy systems to the cloud
  • Consulting
  • Testing
  • Integration

The services are provided by a cloud developer or a software engineering company. They can consult you on what type of platform to choose, the benefits of the given platform, the ways of transforming your data to the cloud, etc. Contacting professionals is recommended as it reduces the risks of implementation and cuts your costs. When it comes to costs for cloud based software development, you should study the rates and salaries of specialists qualified in this domain.

Cloud Developer Salary and Skills

According to Glassdoor, the lowest salary of cloud developers is $50,000, the highest – $120,000 whereas the median is $95,000.

Cloud Developer Salary and Skills

As you can see, the related jobs are cloud architects and other cloud computing specialists. Their inlome is much the same as the salary of developers.

According to CloudTech, the most trending cloud skills in 2017 were as follows:  

  1. Big data and databases.
  2. Apps security.
  3. Enterprise cloud migration.
  4. Containers.
  5. Enterprise cloud software development.

Developers with a strong background in virtualization (Amazon AWS), private clouds hosting, DevOps, IPv6 are in great demand this year.
