Cloud has been around a while now but the deployment models and their use cases are still misty (pun intended). Business models find it hard to analyze the pros, cons, and the need for the three deployment models: Public, Private and Hybrid. This article will analyze the differences, use cases, and real-time examples for each cloud deployment model.
Public cloud is provided by third-party providers and shared across organizations via the internet. Well, according to the raindrops, two make a company, and three make a cloud.
- No responsibility for maintaining hardware and software
- Minimal knowledge is required to set up the cloud and use public cloud resources
- Available to everyone through the internet
- Pay as you go model
- Security is still a question mark in the public cloud
- Regulatory compliance standards might go unmet in the public cloud deployment
- Resource utilization might not be satisfactory since we don’t own the hardware and services
Real-time use cases:
Netflix is by far the best case study for the public cloud. Before 2008, Netflix used relational databases on its own data centers. Storing customer details, preferences, and the thousands of video content, the company eventually faced a major issue in the database in 2008.
With the growing business needs, customer base, and data storage, Netflix had to rethink the data center situation. Being the genius it is, Netflix saw the potential in cloud computing way before cloud was the scene. Netflix migrated its functioning, content, and delivery network to Amazon’s public cloud — AWS. What is interesting is, Amazon has its video-streaming service. Amazon’s cloud has benefitted the streaming service provider by no doubt by supporting the amazingly fast growth in the global market. It has almost 25 times as many streaming members as it had in 2008. It is very rare to see downtime errors in Netflix.
Private cloud is cloud computing that is dedicated solely to a particular organization. It is offered to selected users over the internet through a private virtual network.
- Resilient security and Regulatory compliance.
- Improved Resource Utilization.
- Geographic availability
- Requires expertise in usage and maintenance of the cloud.
- More expensive
Real-time use cases:
To stay ahead of several other competitors, the State Bank of India(SBI) had to up its game to establish relevance with the digitally aware youth. Faster, reliable, and secured payments were the demands of the major consumer market. User growth and the rise of digital modes of payments called for an unparalleled level of change for SBI.
The group opted to take the plunge of IT transformation. SBI uses one of India’s most robust private clouds — “MeghDoot” of about 7500 VMs hosting several financial services applications based on various technologies. Banking applications and services are provided with high availability and scalability.
Leveraging the benefits of both the clouds, a hybrid cloud is a combination of both public and private clouds.
- Best of both worlds
- High availability and Increased security
- Faster migration and increase in proprietary.
- Implementation is difficult
- Security Concerns by third-party vendors
Real-time use cases:
BBC has recently signed a 5-year hybrid cloud contract with Object Matrix after the success of the Planet series. It has been a customer of Object Matrix since 2010 with a MatrixStore on-premise 200TB. After the recent shift of its headquarters, BBC has seen a spike in production.
This called for the up-gradation of its existing On-premise data storage facilities. Also with the current situation of work from anywhere, it needed to ensure that the external team members could access the content effectively. MatrixStore ensures BBC gets the exact mix of On-premise and public cloud.
The upgrade to its existing MatrixStore infrastructure will facilitate the company to protect added content of several on-premise works- functionalities.
Well, cloud deployment models do not stop here. Multi-cloud and community clouds are also considered as a part now.
Multi-Cloud: The difference between hybrid and multi-cloud is foggy for many. Again pun intended :)) Well, a hybrid cloud refers to the pairing of both private and public clouds. A multi-cloud model can include the architecture of a hybrid cloud; however, it is basically the usage of more than a single public cloud. It can use software from one cloud provider and infrastructure from another provider. Community Cloud is a hybrid form of private cloud. They are multi-tenant platforms that enable different organizations to work on a shared platform.
Community Cloud is a hybrid model of the private cloud. They are multi-tenant platforms that enable various organizations to work on a shared platform. The growth of virtual technologies has made Cloud Computing an integral part of every industry. This idea aims to admit multiple customers to operate on shared projects and applications that belong to the community, where it is important to have a centralized cloud infrastructure.
Here is a little quiz on your understanding of cloud deployment models, now is the time to bring your thinking cap on.
1)A small business with 25–30 employees has decided to move its data and working functionalities onto the cloud. They are looking for extremely accessible data, easy data backup, cost-efficient. They also need accounting software, customer service tools. Which deployment model is best suited for the considered business?
Answer: A public cloud system is great for organizations that want more elasticity, cost-effectiveness, and the latest technology.
2)A national bank requires cloud deployment services with high security, privacy, and reliability, allowing only authorized persons to access resources. Which deployment model is best suited for these requirements?
Answer: A private cloud system is flexible, secured, and has high scalability, which allows organizations to customize their infrastructures per their necessities
3) A retail company has websites that require high performance at all times. They have on-premise servers to handle the working, but sometimes during seasons of sales, they experience periods of spikes in traffic. Which deployment model will handle their traffic spikes and also provide the on-premise model?
Answer: Hybrid cloud efficiently handles the on-premise model during the off-season and allows for users to offload overage traffic when their on-premise systems are overloaded.
4) A global company has decided to offer video streaming solutions for business to share their ideas and presentations and pitch them to clients. They wish to adopt cloud scaling to enable larger bandwidth and speed. Which deployment model is best suited for the considered global company?
Answer: Public cloud allows streaming platforms to increase their bandwidth to provide better video streaming performance and viewing experience.
5) An organization wants to build infrastructure designed for users to access books by members through electronic devices. The borrowed books can be verified using the cloud by sharing resources between devices. Which deployment model will help them build such a system?
Answer: Private cloud can come to a rescue when an organization wants to share resources only with its members.
