2015: Suddenly It's Cool To Scale SQL

So it's nearly 2015 and almost all aspects of the application and infrastructure stack can be virtualized and scaled to achieve higher throughput and high availability requirements.  This is also true for the database layer as long as all data can be stored and managed by a single server or virtual machine.  If you are using a traditional relational database as part of the stack, scaling up on a single machine is pretty much the rule unless you are willing to break your database into shards or replicate data across multiple machines. 

The relational DBMS vendors have spent years perfecting workarounds to overcome these inherent limitations in the original architecture of their products.  These systems where designed for the client/server systems back in the 1980s, not for modern datacenters or the cloud both of which embrace a scale-out rather than a scale-up application deployment model.

Using these workarounds to deploy multiple client/server databases as a single, logical, distributed scale-out system work and are proven in production. These systems have been carefully designed and often deployed at enormous expense. They work as long as they don't hit the next wall from a growing user base, database growth, or other scaling challenges.

New approaches to turning SQL databases into truly distributed systems are fundamentally different from the original relational database designs. They look like relational databases from the outside in but from the inside out they are innovative, new architectures that resemble some of the approaches taken by in-memory databases and NoSQL.

2015 is the year that NewSQL database systems are crossing the chasm and will begin supporting true enterprise-scale applications previously based on the big name RDBMS systems. 

2015 will also mark the start of a major shift in how companies and application vendors evaluate migrating business-critical on-premise applications to cloud-based architectures.  The fear that cloud-based deployments of relational database applications won't scale will end.  Other fear factors like data security are perennial and won't cease despite the ability of the new-age distributed databases to provide the same levels of security and encryption mechanisms found in mainstream RDBMS systems today.

NoSQL systems have paved the way for getting distributed systems into the mainstream.  However NoSQL necessitates trade offs between transactional consistency and scalability.  These trade offs are acceptable for various operational and analytical applications that don't require the ACID compliance offered by RDBMS. 

NewSQL systems will pave the way for scale-out performance with SQL. Watch out for big news in this space in 2015.
