Today, with data centers running larger than football fields and computing devices more powerful than the supercomputers 25 years ago, we live in a world where data is the new commodity upon which all businesses rely.
Yes, custom eCommerce web development when coupled with innovative digital marketing techniques can certainly make you stand out and provide an edge over thousand others, but unless you are able to swiftly handle your customers, mediocrity, if not failure is bound to happen.
And it is no coincidence that almost every successful business you see today is connected to cloud in one way or another.
Technology, as many would assume, is a fairly complicated and highly resource intensive thing to create.
And it is simply not feasible or rather possible for each enterprise to accumulate all such technological and computing resources that they might need.
But now you decide to organize a sale every month which is expected to bring 10,000 visitors every hour.
IaaS-based cloud web hosting platforms provide customers with complete control over their web hosting experience, with emphasis put on the operating system used and the resources of virtual machines.
eNlight from ESDS is a prime example of an IaaS implementation because our cloud hosting clients are able to develop their virtual machines with the resource that they wish to see, as opposed to choosing a pre-defined web hosting plan as outlined by other forms of web hosting.
IaaS implementations can provide businesses of all sizes with a variation of benefits such as:The pay per use configuration of this cloud platform basis ensures that customers are only billed for the resources that they are using, along with any additional features purchased to support their VMsScalability is offered through the option to order additional capacity for your virtual machines as demand increases; with eNlight you will also find that auto-scaling is supported providing vertical and horizontal scalingReliability and security are two features that IaaS can offer as additional control can be offered to clients, putting them in a position similar to what a dedicated server provides.Additional control of particular networking components is also a possibility because to some degree it is important for businesses to have control over factors external to their cloud virtual machines.
Popular options chosen by larger users of cloud web hosting can include:Setting up a virtual LAN between multiple virtual machines in the cloud can create a secure communications channel between these serversAccess to routers can be provided to offer load balancing in the cloud for websites that experience high volumes of trafficAPIs can be built into the software layer to offer advanced control of virtual machines from third-party interfaces, whether these are desktop applications or web applications.ESDS utilizes the concept of IaaS with our eNlight cloud hosting services, one of the most advanced cloud hosting platforms available today.
We also offer private cloud solutions for situations where a shared cloud doesn’t provide the desired level of control.Platform as a Service (PaaS)PaaS services related to applications or services that are hosted in a central location where the user doesn’t have control over the operating system layer or any of the hardware involved.
The best example of PaaS is where hosted Microsoft Exchange email Server is offered within the context of a shared platform where multiple users share the same Exchange server environment; here the consumer will have no control over the hardware, OS or application layers, but can create additional email accounts that can access and use the Exchange environment.

Sky Infotech offers Cloud Computing Training in gurgaon, cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.
In cloud computing, the word cloud is used as a metaphor for “the Internet,” so the phrase cloud computing means “a type of Internet-based computing,” where different services — such as servers, storage and applications are delivered to an organization’s computers and devices through the Internet.

Delivering Platform as a Service (PaaS)
Having dominated the business technology landscape for over a decade (as estimated till now), organizations have perfected the art of developing cloud-based apps and migrated on-premises systems into the cloud.
With the services that range from cloud app development to cloud migration to integrate to cloud app containerization, it is practical to optimize current cloud solutions by standardizing outmoded environments, consolidating infrastructures, and modernizing individual resources.
According to Gartner, global public cloud revenue will grow 17.5 Percent in 2019 and this growth will become exponential through 2022.
The cloud application infrastructure services or platform as a service (PaaS) will follow the race and is estimated to grow at a rate of 21.8%
Differentiating Cloud Computing Deployment Models
Ease of setup and use
Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources and economies of scale. You typically pay only for cloud services you use, helping lower your operating costs, run your infrastructure more efficiently and scale as your business needs change. It allows enterprises to get their applications up and running faster, with improved manageability and less maintenance and that it enables IT teams to more rapidly adjust resources to meet fluctuating and unpredictable demand. Below discussion should be noted by investors looking to put money into cloud computing technologies.
Characteristics
- Device and location independence enable users to access systems using a web browser regardless of their location or what device they use.
- Maintenance of cloud computing applications is easier because they do not need to be installed on each user’s computer and can be accessed from different places.
- Multitenancy enables sharing of resources and costs across a large pool of users.
- Performance is monitored by IT experts from the service provider, and consistent and loosely coupled architectures are constructed using web services as the system interface.
- Productivity may be increased when multiple users can work on the same data simultaneously.
- Reliability improves with the use of multiple redundant sites.
- Scalability and elasticity via dynamic (“on-demand”) provisioning of resources on a fine-grained, self-service basis in near real-time.
- Security can improve due to the centralization of data, increased security-focused resources.
Service Models
- Infrastructure as a service (IaaS)
It refers to online services that provide high-level APIs used to dereference various low-level details of underlying network infrastructure like physical computing resources, location, data partitioning, scaling, security, backup etc. IaaS cloud providers supply resources on-demand from their large pools of equipment installed in data centers. Cloud providers typically bill IaaS services on a utility computing basis: cost reflects the number of resources allocated and consumed.
- Platform as a service (PaaS)
Cloud providers deliver a computing platform, typically including operating system, programming-language execution environment, database and the webserver. Application developers develop and run their software on a cloud platform instead of directly buying and managing the underlying hardware and software layers.
- Software as a service (SaaS)
In this model, users gain access to application software and databases. Cloud providers manage the infrastructure and platforms that run the applications. SaaS is sometimes referred to as “on-demand software” and is usually priced on a pay-per-use basis or using a subscription fee.
- Mobile “backend” as a service (MBaaS)
In this model web app and mobile app developers are provided with a way to link their applications to cloud storage and cloud computing services with application programming interfaces (APIs) exposed to their applications and custom software development kits (SDKs).
- Serverless computing
It is a cloud computing code execution model in which the cloud provider fully manages starting and stopping virtual machines as necessary to serve requests and requests are billed by an abstract measure of the resources required to satisfy the request, rather than per virtual machine, per hour.
Deployment Models
Private Cloud
Cloud infrastructure operated solely for a single organization, whether managed internally or by a third party and hosted either internally or externally. Undertaking a private cloud project requires significant engagement to virtualize the business environment, and requires the organization to re-evaluate decisions about existing resources.
Public Cloud
When the services are rendered over a network that is open for public use. Public cloud services may be free. Technically there may be little or no difference between public and private cloud architecture, however, security consideration may be substantially different for services (applications, storage, and other resources) that are made available by a service provider.
Hybrid Cloud
It is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources.
Cloud Platforms & Solution Providers
Cloud services is a rapidly growing market. Modern technologies like big data analytics, IoT, artificial intelligence and even web and mobile app hosting all need heavy computing power. Cloud computing offers enterprises an alternative to building their in-house infrastructure. There are many companies that offer cloud platforms for development, management and deployment of applications.
