1. Private Cloud
One of the biggest advantages of a private cloud database is that it can keep up with the needs and use cases of companies. The fact that the Information Technologies team is under control always increases the belief in security. Emergency recovery processes and security measures should also be included in the solution architecture.
However, it should be noted that; The geographic location of the company is also very important. If users in different parts of the world try to access the system with mobile devices, problems or delays may occur. From this perspective, we can cite financial and health services as an example.
There is one more thing to be said for the private cloud. Before migrating to a private cloud database, the expected return on investment should be reviewed and carefully considered whether it fits your company’s needs.
2. Hybrid Cloud
The first feature of the hybrid cloud is that it is customizable and flexible. Thanks to this database, you can take advantage of the private cloud for some of your functions and allow you to switch to the public cloud if your data amount grows. Recovery solutions, which we call disaster scenario, can also be placed in the hybrid cloud. Thus, you can easily be protected from such situations.
Thanks to the hybrid cloud, companies can also store some of their data locally and upload some to the cloud. However, there is one problem. Maintaining integrity in a hybrid cloud structure is a very difficult task. And it can cause some security problems. If your required processing power grows uncontrollably, you may end up with a hybrid cloud environment that becomes impossible to manage.
If you want to move your company to the hybrid cloud, you should also develop a migration strategy. This issue is very important in transition. You have embarked on such a path to increase your security. However, you should prevent any confusion that may arise.
3. Public Cloud
The biggest advantage of the public cloud is that it can grow to an infinite amount of data and also has a pay-as-you-go model. This will allow a company to go to market faster. The public cloud is homogeneous in its structure. In other words, it is in a structure that can meet the workload of more than one company at the same time. The settings for your needs may cause some difficulties.
As we mentioned while describing the hybrid cloud; In case of uncontrolled growth, it will also cause big problems in the public cloud. If there is no strategy created to manage such platforms, the company’s expenses will constantly increase. Therefore, efficiency will not be achieved.
Another disadvantage of public cloud is data visibility. Because once you upload the data to the public cloud, it is difficult to understand where it is located and in which country it is located. The public cloud can therefore pose a problem for global companies. It is advantageous in terms of operating expenses, but this may change after the first 36 months.
Security will always be an issue if you use the public cloud. To prevent this; encryption of static data and well-designed access management tools should be used.
4. Appliance Database
This database model is a solution that businesses will position in their own locations. The Appliance database can be managed either by the IT team in the company or by the manufacturer. There are many reliable manufacturers for Appliance database solution. If you provide the entire solution with a single manufacturer, you can provide support and performance increase.
However, it also has a bad side. This can leave you tied to a manufacturer. Because device-based databases are used as a situation-specific option. If you are going to switch to appliance database solution; You should make your choice of manufacturer well.
5. Virtual Database
This is a solution most companies use today. Thanks to virtualization, it is possible to combine hundreds of applications on only one hardware. Thus, costs are reduced and resources are used more efficiently. Although the initial expenditures may seem high when you enter this type of structuring, most of your transactions will become automatic and the expenses of your business will decrease over time. Here, your cost decreases but your licensing fees increase.
Virtualized databases provide good data center resource utilization because they take up less space. Savings are also achieved in server operating systems. It allows the creation of multiple virtual databases on a physical server. Virtual environments are already capable of scaling. Their management is also quite simple.
The bad side of virtualization systems is; Unfortunately, virtual machines also break down. You should create your recovery scenario very well when there is any mistake in this regard. It is also an ideal method to evaluate your old equipment. You have the opportunity to combine many of your applications with old hardware. In emergency scenarios, you can easily create your recovery scenarios by creating more than one virtual machine on more than one server.
