There are many advantages to a cloud data center, and they are;
Easy Set-Up
Depending on the requirements of the business, cloud data centers are simple to set up and employ. They offer solutions to make it simple for businesses to start up quickly.
Cost Effective
This is especially advantageous to enterprises or businesses that choose a cloud data center because it is less expensive than a physical setup. More companies are beginning to migrate to cloud services because it eliminates capital expenses, which include - servers, networks, communication equipment, generators, and so on. Cloud services would only require operational expenses, which means you’ll only have to pay for the service depending on how long it's required, and you can turn off systems without any charge.
Reliability
Data centers can be relied upon based on how available they are, even during a disaster. In the case of downtime, there are methods put in place to ensure a quick recovery.
Security
Physical, network, and software-based security measures are established to protect sensitive data. System access controls prevent unauthorized access, and these measures include authentication, multifactor authentication, etc.
Flexibility
The flexibility of the future, adding resources over time without incurring any cost is one of the advantages of cloud data centers. Companies can scale resources without investing in infrastructure. There are varieties of deployment models to choose from, for example, there are public, private, or hybrid clouds, depending on need and requirements.
Back-Up
Individuals or organizations can protect physical data from destruction, such as fire, flooding, or other natural disasters. Storing backup copies of data in the cloud ensures that data is recovered when such an event occurs.
Ownership
The issue of data ownership in the cloud is complex; user owner rights cannot be ensured when data is stored on a cloud provider's infrastructure. Even though users are told that their data belongs to them, this does not always imply that the data is private. A user might be given full control of their data, depending on the data policies and how they classify data in the cloud. And for upgrade functionality, companies must rely on a third-party data center (cloud) in comparison to having their own data center to manage and improve capabilities.
Security Concerns
This can be advantageous and also disadvantageous. Cloud data centers, especially the public cloud, over which you have very little or no control, can raise security concerns. Also, different cloud service providers may achieve and maintain various degrees of data protection and security.
Limited Customization
Companies are unable to add customization to their systems to meet specific needs. Cloud data centers provide pre-configured hardware and software environments, which may limit the control and requirements of an organization.
Latency
Issues regarding latency may arise. Simply put, latency is the time it takes for data to travel from the user's device to the cloud data center. This may not be noticeable, however, engaging with applications such as gaming or video conferencing exposes latency issues, resulting in a poor user experience.
What types of cloud data centers are there?
The three types of cloud or deployment models are:
1. Public Cloud
Public cloud centers are accessible to anyone, and to use this service, you only pay for the resources depending on how long you need them. This type of model is controlled by the cloud service provider, you may know the region where the infrastructure is located, but you’ll be unable to access it or control what happens with your data. Examples of public cloud include; Blue cloud and Sun cloud(IBM), Microsoft Azure, and AWS.
2. Private Cloud
Private cloud is operated by or for a single organization. This is a controlled type of cloud deployment where you know where the physical servers reside. Private cloud data centers can be managed by the organization or third party that may either be on premise or off-premise e.g. AWS, VMware, etc.
3. Hybrid Cloud
Certain information needs a certain environment, the hybrid cloud combines both public and private cloud functionalities. Companies may use a public cloud provider like Microsoft Azure to run their website or customer-facing application while using a private cloud for sensitive data and applications that require a high level of protection.
