Cloud computing depends upon the same physical server hardware that is the backbone of any computer network. The cloud architecture enables the availability of the processing power and storage capacity of the hardware over the internet. This gives cloud providers the ability to utilize servers that are distributed around the world for forming a robust and consolidated computing network that users can access from any internet connection. You can easily hire cloud application development companies in India at affordable packages.
Types of Cloud Development:
Cloud deployment is the way a cloud platform is implemented, the way it is hosted, and who all are allowed to access it. All the cloud computing deployments function on the same principle via virtualization of the computing capability of servers into vividly segmented and software-driven apps that bring processing and storage capabilities.
1. Public Cloud:
A few examples of public cloud would include public clouds provided by Amazon, Google, or Microsoft. These organizations offer both the services and the infrastructure, that all customers can share among them.
Public clouds typically come with massive space that is translated into easy scalability. A public cloud works best for software development projects along with collaborative projects.
Companies can design their applications to make it portable, so that the project that a user tests in the public cloud can be moved to the private cloud for enabling production.
Most cloud providers offer their computing resources as a part of their service. Instances of public cloud would range from access to an entirely virtual infrastructure providing a little more than raw processing power and storage to specifically specialized software programs that are easy for implementation and use.
The main advantage of the public cloud is that it comes with great versatility and a ‘pay as you go’ structure allowing users to provide more capacity on demand.
Also, the very essential infrastructure and operating system of the public cloud stay under full control of the cloud provider.
Users can continue to use the platform under the terms and conditions that the provider has laid out. But they may face some difficulty with repatriating their assets if they wish to change service providers.
If the provider goes out of business, or makes prominent changes in the platform, customers may be forced to make essential changes on just short notice.
2. Private Cloud:
Private clouds typically reside behind a firewall, and a single organisation uses it. For businesses that come with very tight regulatory requirements, an entirely on-premises cloud is a preferable solution, even though private clouds implemented via a colocation provider will win in popularity.
Only authorised users will be able to access, utilize, and store data in the private cloud from any location, just like they can with a public cloud.
The difference here is that no one other than the authorised users can access or utilize these computing resources.
Private clouds ensure security and control, but users will need to pay a cost to enjoy these beneficial functionalities. The company owning the cloud will be responsible for both the software and the required infrastructure, that makes private clouds a less economic model as compared to the public cloud.
Private cloud offers an additional control that makes it able to restrict the access to valuable assets and makes sure that a company is allowed to move its data and application whenever and wherever it wants.
Since any external vendor does not control the private cloud, there remains no risk of sudden changes that would disrupt the whole infrastructure of the company.
Also, the downtime of a public cloud provider will never be able to affect a private cloud solution. But private clouds do lack the versatility that public clouds come with.
A user can expand a private cloud only by adding more physical computing and storage capacity increasing the difficulty of scaling operations quickly in case such a business need arises.
3. Hybrid Cloud:
The first and foremost advantage of a hybrid cloud solution model is that It comes with the ability to provide scalability in terms of the computing power that comes with a public cloud, along with the security and control provided by a private cloud.
Users can store data safely behind the firewalls and the encryption protocols provided by the private cloud; then the users can move it securely into a public cloud environment whenever required.
This factor helps a lot in the current age of big data analytics, when industries like, for example, healthcare, are bound to adhere to rigid data privacy regulations while inputting sophisticated algorithms powered by artificial intelligence (AI) to extract actionable insights from huge volumes of unstructured data.
There are two main types of hybrid cloud architecture that are popular in use.
The first type is Cloudbursting that uses a private cloud as the primary cloud for storing data and housing proprietary applications within a secure environment. When the service needs to be increased, the infrastructure of the private cloud may not have the capability to keep up.
This is where the public cloud makes an entrance. A cloudbursting model uses the computing resources of the public cloud to supplement the private cloud. This allows the company to manage increased traffic without buying any new servers or infrastructure.
The second kind of hybrid cloud solution also runs most of the applications and stores most of the valuable data within a private cloud environment. But it outsources non-complicated applications to a public cloud provider.
This arrangement is very common among organizations that have the need to access specialized development tools e.g., Adobe Creative Cloud, basic productivity software like Microsoft Office 365, or CRM platforms like Salesforce.
The multi-cloud architecture is mostly deployed here while incorporating multiple cloud service providers for meeting a variety of unique business needs.
Three main types of Cloud Computing Services:
1. Infrastructure as a Service-
IaaS stands as the foundation of the cloud computing pyramid and it is the most comprehensive and flexible type of cloud service.
It offers an entirely virtualized computing infrastructure that is provisioned and handled over the internet. An IaaS provider handles the physical end of the infrastructure in a data centre, while allowing customers to wholly customize the virtualized resources to fulfil the specific needs.
The user can buy, install, configure, and manage any software that they need to use with IaaS, along with the components like operating systems, applications, middleware, developmental tools, business analytics.
It is highly scalable and users pay only for the infrastructure they will be using. This allows them to scale their computing requirements whenever the need arises, without building any additional capacity.
IaaS eliminates the capital expense of building the in-house infrastructure and it is a great choice for small companies and start-ups that do not have the resources for buying the hardware and software that is required for building their own network internally.
It also takes the daily burdens of handling computing infrastructure off the IT departments hands, allowing them to focus on the core business drivers in place of troubleshooting.
The IaaS provider updates their system continuously with the latest software and updates. Hence, it is easier for users to get new programs and applications running.
IaaS offers the latest security protections along with services like recovery of disaster to go hand in hand with their uptime reliability SLAs.
Examples would include Amazon Web Services, Cisco Metacloud, Microsoft Azure, Google Compute Engine.
2. Platform as a Service:
Placed little bit higher on the cloud computing pyramid is PaaS. While IaaS offers all the tools available through the cloud and it is up to the customer to build whatever fulfils their needs, PaaS is more specialized.
Instead of a pure infrastructure, PaaS offers the framework required for building, testing, deploying, managing, and updating software products.
PaaS uses the same basic infrastructure that IaaS uses but it also comprises of the operating systems, development tools, middleware, and database management systems that users need for building software applications.
PaaS is extremely useful for any company that develops software and web-based applications. Many tools that help in developing multiple platforms can be expensive.
PaaS users can access the developmental tools according to their requirement whenever they need, without buying them outright.
Remote development teams can access the same assets for speeding up the product development process. Most PaaS tools come with extensive pre-coded apps built into the platform, which can reduce the coding time and assist companies in marketing their products faster.
Examples would include AWS Elastic Beanstalk, Google App Engine, Apache Stratos, Microsoft Azure.
3. Software as a Service:
SaaS is the most familiar form of cloud computing and it stands on the top of the pyramid. It is a wholly-developed software solution ready to be bought and used over the internet on a subscription basis.
The SaaS provider takes care of the infrastructure, middleware, operating systems, and data, required for delivering the program, making sure that the software is available whenever and wherever the user needs it.
Several SaaS apps runs directly through web browsers removing the need for downloads/ installations. This reduces software management issues for internal IT teams and allows companies to streamline their tasks with hybrid and multi-cloud deployments.
SaaS allows companies to get running very fast and also scale operations very fast. They will not need to buy or deploy the hardware and software for delivering their business services.
Even enterprise-level apps like CRM or ERP programs can be accessed easily by the smallest organizations, offering tools that allow users to enhance the growth of their business more effectively.
Examples would include Microsoft Office 365, Cisco WebEx, Salesforce, Google Apps.
