Database as a Service (DBaaS) is a category of cloud-based computing managed services that provide access to a database without the need to establish physical hardware, install software, or configure the database. Instead, the service provider handles most database administration and maintenance tasks. Users can quickly start up a database and load and analyze data, typically with little or no IT intervention.

Why is DBaaS important?

DBaaS is important to the larger corporate initiative of digital transformation in which companies fundamentally change how they operate and deliver value to customers. Specifically, companies striving for greater data democratization might choose DBaaS as a way to deliver on an any analytics, any time strategy. Also, organizations concerned with ESG (Environmental, Social, and Governance) advances can leverage the DBaaS ability to spin up and down servers at will as a way to save resources.

Advantages of DBaaS

DBaaS offers some advantages over traditional methods to deploy database systems, including the following:

• Abstract physical architecture from your organization – The vendor and its partners provide the hardware needed for running the workload, removing the need for your organization to maintain servers.
• Reduce hardware and database software upgrade costs – As the infrastructure is no longer on-premises, organizations no longer have to invest in database servers or plan time consuming hardware upgrades.
• Reduce capital expenditures – As-a-Service software allows an organization to move some expenses from capital expenditures to operating expenditures. Doing so makes future spending more predictable, lowers capital costs, and reduces your need to spend money on hardware and software.
• Streamline database management – DBaaS providers handle many routine database management and administration tasks, and this too can lower operating costs.

Disadvantages of DBaaS

There are also potential disadvantages with DBaaS compared to on-premies databases.

• Savings are not automatic. Some companies have run the numbers and found DBaaS significantly more expensive for specific workloads. Savings seems to be best achieved on ephemeral workloads rather than persistent ones, as the cost-benefit of DBaaS is amplified when analytical workloads are not running.
• Lack of control. With managed databases, an organization’s IT team may not have complete access to a server’s features, as they too, are abstracted away. Users must rely on the cloud provider to fully manage the infrastructure effectively.
• Reliance on fast internet. If an organization’s internet connection is weak or experiences outages, the organization won’t have access to its database until the problem is repaired. In addition, organizations may experience slow query times due to internet speed.
• Security. Some buyers of IT prefer to have direct influence over the safety of the servers running its databases. Although public cloud security is known to be fairly strong, the vendor is in charge of securing the database platform and underlying infrastructure. Security is also abstracted away on some level.

Categories of DBaaS

There are a number of types of DBaaS providers, making for an extraordinary and diverse range of options in the DBaaS space.

Public cloud providers

Many cloud vendors like Google, Azure and Alibaba have their own DBaaS offerings. Users can leverage the same account they may use for computing and storage to instantiate databases.

• Pros

  • Simplicity in billing and in deployment
  • Many capable options

• Cons

  • Lock-in
  • Must use a single cloud
  • Difficult to transfer workloads in hybrid environment
  • Fees to egress data
  • External tables are harder to leverage

Proprietary cloud vendors

Vendors like Snowflake, Firebolt, and others offer a proprietary cloud, where users pay the vendor for both the use of the database and use of the cloud services. The database and servers are provided by the vendor, although the servers and storage are outsourced to a public cloud provided through the vendor contract.

• Pros

  • Simplicity in billing and in deployment
  • Many capable options

• Cons

  • Lock-in
  • Fees to egress data
  • Server costs are negotiated by the vendor and may be marked up when sold to you
  • Often built for cloud-only

Partner DBaaS companies

Many amazing options for DBaaS also appear in the partner marketplace of the public clouds. Users contract with the DBaaS partner and the cloud provider separately. These vendors, including Vertica, often offer options.

• Pros

  • Often available on multiple clouds and easier/cheaper to support multicloud
  • Often have deeper or specialized functions to ease development on certain workloads
  • No lock-in
  • Often work both cloud and on-premises

• Cons

  • Need to manage multiple vendors for billing and licensing

What to look for in a DBaaS?

Beyond the types of DBaaS, there are other major differences between DBaaS providers, including:

DBaaS deployment options

Does your DBaaS also offer non-SaaS deployment? Some DBaaS vendors require you to lock into a specific storage place in one particular cloud. This locks the customer into one cloud, not allowing the freedom to move to a different cloud easily or take advantage of lower-cost cloud computing when available. Some vendors offer no solution for on-premises analytics or deploying in . Weed out vendors who don’t support all of your deployment needs.

Licensing flexibility

Does your solution offer a license that allows you to easily move between multiple clouds or on-premises, or are separate licenses required for each deployment? What are the costs to maintain DEV, TEST, BACKUP and PRODUCTION? Take a look at total costs to understand which vendors will meet your needs.

Data lake capability

Do you often have locally-stored Parquet, Orc, AVRO, JSON or TEXT files that you need to incorporate into your analytics? When choosing your DBaaS vendor, explore how it can bring together a data lake’s scale and economics with the predictability and reproducibility as a data warehouse. In addition, consider how well your solution understands external table workloads and how much data movement is required.

Ability to optimize

Does your DBaaS operate in a limited compute package? All analytics is not the same, nor should it be considered the same. Make sure that the database that you select has options to properly manage all types of workloads and service level expectations. 好色先生TV that do node-based optimization (simply adding generic nodes when your workload calls for it) may cause you to miss out on methods to keep your cloud costs lower while improving query performance at the same time. The capability to use specialized nodes, and the ability to tune slow queries is paramount.

Depth of analytics

Can you leverage your DBaaS for more than just descriptive analytics? Today’s data-centric companies have analytical needs that reach beyond standard SQL databases. For example, some workloads call for advanced analytics like geospatial, or time-series function. Predictive analytics is becoming increasingly imperative to data science teams, so consider how machine learning is supported. Consider how your solution can support a wide range of analytical use cases and a wider team of professionals as your cloud database gains success in your organization.
