The previous post covered SaaS vs PaaS vs IaaS: What’s the Difference & How to Choose
DBaaS (Database as a Service)
You rent a completely configured database from the cloud provider. This service is often purchased in combination with Infrastructure-as-a-Service (IaaS). The cloud provider is responsible for management, updates, and performance. This service is most similar to PaaS but contains a significant difference.
With a DBaaS, developers have access to the underlying database, allowing them to choose a database technology that suits the application. The advantage is that you can get started immediately and continue even without database expertise. Moreover, you can quickly switch resources. The disadvantage is that you have less control over the configuration and virtually no tuning possibilities. Examples: SQL Azure, AWS RDS, Postgres
DBaaS is fast, flexible, and already configured out of the box by default. You have access to unlimited resources. There is also less, or no, DBA expertise required. However, the costs can quickly and gradually increase when additional services are purchased and resources are scaled up. There are limited possibilities to apply custom configurations, as well as tuning specific settings.
The supplier takes care of all management and maintenance, so you don’t have to worry about that, but you cannot also change or alter the software.
BaaS (Backup as a Service)
BaaS is a cloud service where the vendor provides a backup where the data is stored in the cloud. Many IaaS, PaaS, and SaaS services offer additional BaaS services. But it is also possible to purchase a BaaS service for an on-premise environment. For example, you can host a server in a traditional data center where the backup service is based on a cloud service. The advantages are that the data is at a different (secure) location, and you do not have to take into account for the management of the backup program. The vendor is responsible for this, as well as upgrading and patching.
Another advantage is that you do not have to invest in licenses and storage. You only pay for what you need, so you don’t have to anticipate possible growth in the coming periods. Many companies often find it challenging to estimate how much storage they should purchase when purchasing storage for their backup environment. In the beginning, you have an excess of storage that is not used, and in the end, you run out of storage and often have poor performance.
Additionally, you are not required to purchase licenses in any minimum quantity or maintenance contracts.
An example of BaaS is the Vembu Cloud BDRSuite. With this Cloud BDRSuite, you can make online backups of any Windows, Linux, or macOS. Even a direct cloud backup of a NAS is among the possibilities! So you can easily create a local backup of your NAS and replicate it to the cloud. If the NAS has a hardware issue, you can still access your data!

BaaS is an uncomplicated and very effective cloud service that offers many benefits. By using BaaS, you can save a lot of money, and you don’t run the risk of backup problems that are often noticed too late.
DraaS (Disaster Recovery as a Service)
With DRaaS (also called Recovery as a Service or RaaS), an organization has an immediate fallback option in case of any potential disaster. Critical data is continuously replicated, and companies can immediately fall back on a recent backup so that work can continue without data loss. A good DRaaS service is regularly tested and evaluated.
DRaaS is a more comprehensive service than Backup as a Service (BaaS). With DRaaS, not only is the data and applications secured and restored but the computer capacity is also provided to get back up and running as quickly as possible.
An advantage is that when using DraaS, the continuity of an organization is always guaranteed. After all, the backup data is available and the current situation is restored. Also, the organization does not have to invest in hardware and software or keep up with specific DraaS knowledge. The vendor has excellent, up-to-date knowledge of this and uses it daily. As mentioned earlier, the backup data is stored in the cloud. These are stored redundantly and in a secure location.
A DraaS service is a (technical) service that needs to be well thought out. Which services need to be replicated, and which services depend on each other? In a disaster, things that have been replicated can be started up in the cloud or at the original location. This offers additional benefits. A company can be back on the air so quickly. However, this process must be tested regularly and preferably incorporated as a disaster recovery (DR) plan.
For example, how do you deal with the fact that in the event of a disaster, the backup server is also no longer available?
It may be interesting to take a look at Vembu Cloud DR. With Vembu Cloud DR, it is possible to store copies of all backups in the Vembu Cloud, which resides in AWS. In addition, this hybrid cloud deployment offers the possibility to always perform a restore, even if the original backup server or environment is no longer available. These copies of backup data can be restored from anywhere at any time.
In the same lineup, Vembu also offers Vembu Offsite DR software that can be downloaded from the Vembu BDRSuite backup server and installed on a physical machine or on your own cloud instance running the Windows or Ubuntu server operating system and also has the option to have your own cloud storage as a storage repository in order to comply with the international and national data protection standards.
These restores can be written to the original location or directly to a cloud provider. Data transport in all the above-mentioned products is fully encrypted, and they also offer support in making a disaster recovery plan.
