Is cross cloud deployment really necessary. What are the four types of cloud computing deployment models.
Before coming to this topic of various cloud computing deployment models, let us get a closer look on what exactly cloud computing is!
Cloud Computing is basically a model of computing where you rent computers, software and networks from service providers. They maintain the computing hardware and software in their data centers, and you connect to them over the Internet. It has the benefit of providing pre-built, provider-managed facilities that you can simply integrate and use, without having to install, configure, or maintain them
Below are some of the cloud computing deployment models
Public cloud deployment- It is one of the best cloud computing deployment models identified by the characteristic that you don’t own any hardware or infrastructure, all your resources are provided to you by a cloud service provider. “Public” in this model means that such a cloud is available for the general public, and resources are shared between all users. For eg Amazon Web Services (AWS).
Private cloud deployment- Well! you could give it a guess by looking at the name itself. The Difference between private and public cloud is in how you handle all of the hardware. Often known as the “internal cloud” which refers to the ability to access systems and services within a given boundary or an organization.
Hybrid cloud deployment- Hybrid cloud deployment involves a combination of both private and public services.They work as one system. This model allows for a smooth transition into the public cloud over a longer period of time. Due to security requirements or data protection, some companies can’t operate only in the public cloud, so they may choose the hybrid cloud to combine the requirements with the benefits of a public cloud.
Multi cloud deployment services- In multi-cloud, instead of combining private with public, you’d use more than one public cloud. The motivations for a multi-cloud deployment are for redundancy or to optimize cost for preferred technology choices.
Community cloud deployment- It is one of the cloud computing deployment models where it has been set up for a particular group of people or a community. For example, a community cloud could be a cloud that a few different banks use. The biggest advantage of a community cloud is the fact that it can be tailored to requirements for a specific “community.” In fact, you might even think of this as a gated community, it’s not private, but within that community are generally a group of similarly interested or invested consumers.
These are some of the cloud computing deployment models. All these cloud computing deployment models have got different attributes.
A cloud deployment model represents a specific cloud environment, primarily distinguished by ownership, size, and access. There are four cloud deployment models:
Public cloud
Private cloud
Community cloud
Hybrid cloud
Each cloud deployment model fulfills different organizational needs, so you must choose a model that will fulfill your organization’s needs.
A cloud deployment model defines the cloud services you are consuming and the responsibility model for who manages them. It represents your cloud architecture, the scalability of your computing resources, what you can change, the services provided to you, and how much of the build you own.
The 4 cloud computing deployment models are as follows:
Public cloud: According to the name, this type of cloud computing deployment model supports all those users who want to use computing resources, such as hardware like OS, CPU, memory, storage, and software like application server and database on a subscription basis. The most common uses of public clouds are for application development and testing, non mission important tasks like file sharing, and e-mail services.
Private cloud: As per the name, A private cloud refers to a cloud deployment model operated exclusively by a single organization, whether physically located at the company’s on-site data center or managed by a third-party provider. Private clouds are costlier than public clouds because the capital expenditure is involved in acquiring and maintaining them. However, private clouds can better address the organizations’ security and privacy concerns.
Hybrid cloud: It refers to a private and public cloud’s interconnected infrastructure. Most organizations use this model when they need to scale up their IT infrastructure quickly, such as when exploiting public clouds to enlarge the capacity in a private cloud. For example, if an online retailer needs more computing resources to run its Web applications during the holiday season, it may attain that resource through public clouds.
Community cloud: This deployment model supports multiple organizations sharing computing resources that are part of a community. For example, universities cooperate in specific research areas or police departments within a country or state, sharing computing resources. Access to a community cloud environment is typically restricted to community members.
When it comes to cloud computing, we have access to a shared group of computer resources ( programs, servers, storage, and so on) in the cloud. You simply need to ask for additional resources when you require it. Following are some cloud computing deployment models.
1. Public Cloud
One of the most commonly used cloud computing deployment models.The public cloud makes it possible for anyone to access systems and services. This cloud may have less security as it is open for the whole public. It is one in which cloud infrastructure services are provided over the internet for the general public or major industry groups. In this form of cloud , storage backup and retrieval services are given for free, as a subscription, or on a per-use basis. Example: Google App Engine etc.
2. Private Cloud
The private cloud deployment model is opposite of the public deployment model. It’s a one to one environment for a single user (customer). It is also called the internal cloud and it means the ability to access systems and services within a given border or organization. This cloud platform is implemented in a safe environment that is protected by powerful firewalls and under the supervision of an organization’s IT section.
It gives the greater flexibility of control over cloud resources.
3. Hybrid cloud
It acts as a middleman between public and private cloud systems with a layer of . With its help you may host the app in a safer environment while taking advantage of the public cloud’s cost savings. Companies can move data and applications between different clouds using a combination of two or more cloud deployment methods, depending on one’s needs. This is one of those cloud computing deployment models where you have the facilities of both.
4. Community cloud
Personally, it is one of my favorites and is definitely in the list of best cloud computing deployment models. It is a distributed system that is developed by integrating the services of different clouds to address the specific needs of an industry and community. It is usually managed by a third party or by the combination of one or more organizations in the community. The infrastructure of the community can be shared between the organization which has shared tasks or concerns.
5.Multi-cloud
It is similar to the hybrid cloud deployment approach, which combines public and private cloud models. Instead of combining private and public, Multi-cloud uses many public clouds. Although public cloud providers provide numerous tools to improve the performance of their services, problems still occur. It’s quite uncommon that two distinct clouds would have an incident at the same moment. As a result, It improves the high availability of your services even more.
These are some of the cloud computing deployment models. These cloud computing deployment models are different from one another and are efficient in their own way.
