An organisation is ready to adopt DBaaS the moment they are ready to address their database management issues.
Could you share some tips on developing a good DBaaS strategy? And what should Asian organisations look for in a DBaaS solution?
For successful adoption and sustainable execution, it is important to understand how DBaaS fits into the overall environment. The greatest value will be reaped when your DBaaS strategy is considered along with the organisation's overall enterprise architecture and IT strategy. Enterprise architecture helps to structure DBaaS projects through a series of overlapping steps, or iterations. A systematic process determines how these environments should be created, with attention to the business, technical, and operational implications.
For example, if the HR department wants to implement a new payroll service and share it with other departments, the enterprise architecture team needs to begin by creating use-cases that reflect the needs of each department. They then consider the profiles of the various departments and develop a service catalogue that lists the functions these agencies need. Then each department can provision as little or as much of each service as needed and also specify the degree of availability, disaster recovery, and uptime requirements.
Oracle has developed a complete Database as a Service Reference Architecture that consists of artefacts, tools and samples that help companies understand how to operationalise DBaaS with attention to the correct strategy, people, processes, and technology.
Within Asia, organisations are generally very process-oriented. This is a good starting point to embark on a DBaaS solution. DBaaS comes in to further simplify processes and to add "oil" to the "gears/processes" of the organisation to improve workflow efficiency and boost business productivity.
According to an Imperva report, DBaaS could be used by hackers to compromise an organisation's database without accessing its network, thus increasing the risk of a data breach. What are your thoughts on this? How should organisations using DBaaS solutions reduce this risk?
Security threats have always been a concern when it comes to hosting information offsite. However, just by making security more fundamental to computing and including it at the database level -- rather than only in the application -- all applications can inherit that security. Having multiple security levels further enhances data protection, enabling reduction in the risk of compromising one's data.
Secured multi-tenancy is one such level of deterrence. By maintaining databases in separate containers, this creates a virtual moat that makes it harder for hackers to access all information at once.
Not only do security settings and service level agreements (SLAs) apply across tenants, SLAs can also be applied to individual tenants/containers to ensure that only role-assigned individuals are granted access.
