on a pay-per-usage model where one only pays for usage and resources are managed and distributed as and when they are used or needed. It provides you the freedom and better functionality to run your codes, deploy apps, be cost- effective without the hassle of managing the servers. Take a look at this intriguing stat by Markets and Markets: OVERVIEW “The cloud storage market size is estimated to grow from USD 23.76 Billion in 2016 to USD 74.94 Billion by 2021, at a CAGR of 25.8% from 2016 to 2021.”
achieve the business agility you need to improve the organization’s overall efficiency, lower costs, and foster innovation via these three models: 1. Infrastructure as a Service (IaaS) Pay-as-you-go for services such as storage, networking, and virtualization. 1. Infrastructure as a Service (IaaS) Cloud Computing: 3 Key Service Models 2. Platform as a Service (PaaS) 3. Software as a Service (SaaS) 2. Platform as a Service (PaaS) Hardware and software tools available over the internet. 3. Software as a Service (SaaS) Software that’s available via a third-party over the internet.
u c t u r e a s a S e r v i c e ( I a a S ) In the IaaS model the client is given access to virtual components to build their own IT platform. This includes virtual server space, network connections, IP addresses and bandwidth. The external service provider gives the hardware to the client and manages it for them. I n f r a s t r u c t u r e a s a S e r v i c e ( I a a S ) 1. Infrastructure as a Service (IaaS)
Scalable On demand availability of resource, hence there are no delays in expanding capacity or any wastage of unused capacity. No hardware capital expenditure: Since the hardware is maintained by the cloud provider, it saves both time and money. Pay-per-usage: Since the service is accessed on demand, the user only pays for the resource that is used. Accessibility: The service can be accessed from anywhere as long as the security protocols are met.
a S e r v i c e ( P a a S ) PaaS is a step ahead from IaaS. In this model, the service provider takes care of everything from the hardware, the cloud server and the supporting software, everything that is needed for application development. This is mainly possible since the service provider hosts the hardware and software on its own infrastructure, thus it frees the users from any kind of hardware or software installation. P l a t f o r m a s a S e r v i c e ( P a a S ) 2. Platform as a Service (PaaS)
As the provider is responsible for infrastructure and IT services, the users have the convenience of access via web browser from anywhere. Pay-per-use This model is preferred by entrepreneurs as it removes the major expense of having an on-premise hardware and software Easy deployment The platform allows you to test and implement new solutions, test it, try different configurations and perfect it. Scalable The service provider can customize the infrastructure as per the client’s demand, hence maintaining the overall service quality. Simple and Convenient
a S e r v i c e ( S a a S ) SaaS allows the user easy access over the internet without the hassle of installing and maintaining software, thus there is no additional requirement of software and hardware management. Software vendors host the servers; code and database that is the part of the applications and the users can access the data from any device that is connected to the internet via web browser. S o f t w a r e a s a S e r v i c e ( S a a S ) 3. Software as a Service (SaaS)
Accessibility Low Cost Multitenant Architecture On demand availability of resource, hence there are no delays in expanding capacity or any wastage of unused capacity. Easy to Customize and upgrade Since the hardware is maintained by the cloud provider, it saves both time and money. Accessibility Since the service is accessed on demand, the user only pays for the resource that is used. Low Cost The service can be accessed from anywhere as long as the security protocols are met.
to the evolution of Serverless platform. The platform operated on the logic that the servers functioned behind the applications and were not visible on the front-end. The small chunk of independent codes invoked by Serverless computing can be executed as and when needed. Such events run the cloud computing services, which translates to the cost of the operation on cloud platform.
of BaaS (Backend –as-a-Service) where all the behind the scene applications of app development are outsourced and FaaS (Function-as-a- Service) that allows developers to write codes which are executed as and when they are required. FaaS acts as the gatekeeper when the user accesses the database and BaaS allows operation without the backend resource management.
of ‘as-a-service’ models. Each model has its specific functionalities and features, it is still very important to study the differences. Looking at the surge in data loads, more and more companies will eventually make the shift, making the future extremely digitized. It does not matter which option you choose, migrating to cloud is the way of the tech world and businesses today!
