What is cloud computing? When to use a cloud?


Hi Friends, Sorry i was quite busy from previous couple of months So don’t get time for post. It’s really great experience working on cloud computing, basically on PaaS(Platform as a Service), BaaS(Backend as a Service) and IaaS(Infrastructure as a Service) with ShepHertz. I came across multiple questions, people asking about cloud computing segment. So i thought of write a blog on Cloud Computing.

Let me explain cloud computing segments in details to understand Cloud Computing.

Cloud computing: Cloud computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

Cloud Computing Segment:

IaaS(Infrastructure as a Service) – Infrastructure as a Service is a provision model of cloud computing in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis. Ex- Amazon Web Services, BlueLock, Cloudscaling and Datapipe

PaaS(Platform as a Service) – Platform as a Service is one of the GROWING sector of cloud computing. PaaS basically help developer to speed the development of app, saving money and most important innovating their applications and business instead of setting up configurations and managing things like servers and databases. In one line I can say Platform as a service (PaaS) automates the configuration, deployment and ongoing management of applications in the cloud. Ex: Heroku, EngineYard, App42 PaaS and OpenShift

SaaS(Software as a Service) – Software as a Service, SaaS is a software delivery method that provides access to software and its functions remotely as a Web-based service. Ex: Abiquo’s and Akamai

BaaS(Backed as a Service) – Backend as a service (BaaS), also known as “mobile backend as a service” (MBaaS),is a model for providing web and mobile app developers with a way to link their applications to backend cloud storage while also providing features such as user management, push notifications, and integration with social networking services. Exp: Kinvey, StackMob, App42 API and Parse

Hopefully this post makes it much easier to understand cloud computing. Let me know in the comments if you love it or find any difficulties to understand.

Some insights into PaaS market


Platform as a Service is a one of the GROWING sector of cloud computing. PaaS basically help developer to speed the development of app, saving money and most important innovating their applications and business instead of setting up configurations and managing things like servers and databases.

Other features buying to use PaaS is the application deployment process such as agility, High Availability, Monitoring, Scale / Descale, limited need for expertise, easy deployment, and reduced cost and development time.

PaaS Market

Major forces driving the PaaS

– Pay as you Go
– Low start up cost
– Leave the plumbing to expert
– PaaS handles auto scaling/descaling, Load blancing, disaster recovery
– PaaS manages all security requirements
– PaaS manages reliability, High Availability
– Paas manages manay third party addon’s for you

Barrier to PaaS adoption?

– Less Control over Server and databases
– Have to be expert to mange security controls and audits
– Costs will be very high if not governed properly
– Premature and dobious in current day and age

Major PaaS providers are Heroku, App42 PaaS , Jelastic, and Engine Yard. When we talk about revenue, The global PaaS market is estimated to grow from $1.28 billion in 2013 to $6.94 billion in 2018 at a compound annual growth rate (CAGR) of 32.54% in this period. In terms of geographies, North America continues to be the biggest market for PaaS solutions. In 2012, PaaS revenues ($1.2 billion) was the tenth of the size of SaaS ($14.4 billion), a fifth of IaaS ($6.2 billion), and just a tiny fraction of BPaaS ($84.1 billion).

PaaS has always taken a very small space in the cloud computing arena as compared to the other two segments: IaaS and SaaS. But the trend has recently shown a drift with PaaS market showing a very high growth rate in terms of revenue. Though it is still not as huge as the other two segments but now holds a significant proportion of the pie. PaaS has now been adopted by most of the big cloud computing and IT solution providers like Amazon, IBM, Google etc. as one of their main services.. Many small players have also emerged and made the market very dynamic and competitive. Application developers are benefiting from this fact resulting in more adoption and thus increasing the demand for PaaS all the more in various sectors.

We expect to see more and more application development companies choosing PaaS over IaaS or traditional Hosting, as they can then focus on driving innovation and building apps that change their interactions with customers, partners and community. It will make them free of the details of infrastructure, so they can push the possibilities of the latest technology to build great web and mobile applications.
