The DevOps Database | Part 2

Applying Systems Thinking to Database Change Management

In my first post in this series, I discussed the underpinning principles of all DevOps patterns as eloquently stated by Gene Kim, author of "The Phoenix Project."  In this post I'd like to dig a little deeper into The First Way.  As a refresher:

The First Way: Systems Thinking - This Way stresses the performance of the entire system of value delivery.  Instead of becoming laser focused on the part of the process for which an individual or team is responsible, the individual or team works to understand the entire process from requirements generation to customer delivery.  The goal is to eliminate the delivery impediments that arise when a project transitions from one isolated silo to another.  Understanding the entire system allows business, development, and operations to work towards a common goal in a consistent manner.

When we started Datical, our first step was to perform extensive market validation.  We quickly learned that database schema management was going to be tough nut to crack. In the scores of conversations we had with people throughout the ALM spectrum, we learned that the process for managing and updating the database schema that supports an application was at best murky and at worst a black box.  So how do we elevate a process owned and understood by a few people in an organization to the level of visibility required to understand that process as part of a larger system?

What follows is a list of concepts pertaining to System Thinking that we've rallied around in providing our database change management solution Datical DB. Instead of the black box, database change management can become a transparent and flexible part of your value delivery system.

Start With Reality
When beginning a new project based on previous development, don't rely on a stack of SQL scripts on a file server or even in a source code control system. As you know, databases evolve over time and sometimes out of process changes happen.  When a database schema is modified to resolve an error condition or performance degradation, these alterations are usually handled in a support ticketing system.  You can never be certain that they were added to the stack of scripts used to build out a fresh environment.  In light of this, any database change management solution should start by generating a baseline from the working system: your production schema.  This ensures that design and development activity are taking into account not only those schema objects generated in Dev, but also those which originated in other stops in the system.

Don't Script! Model!
To keep this blog post short(er) I'll point you now to a blog post I wrote a few months ago on modelling vs. scripting.

Version Twice, Deploy Once
The first level of versioning any database change management tool should provide is versioning of the gold standard. Versioning the scripts or model that you use to build a fresh database instance for your application provides a ton of benefits.  You can track how your schema has evolved over time and across releases, you can tightly couple a schema definition to the version of the application it supports using the same branch/tag/merge workflow that you use for your application code, and you can quickly stand up a new database instance that you know is correct for any released version or experimental branch you are working in.  The second level of versioning takes place in each database instance.  Tracking the version of the schema deployed on a specific instance makes deployment and troubleshooting much easier.  Will this application build work with the schema on this instance?  What changes need to be applied to this database to catch it up to the latest version?  Were the right changes applied to this test database to validate a closed defect?  If you are tracking the individual changes applied in a database and the impetus for those changes, these questions can be answered quickly and easily.

Unify Your Modes of Delivery
We've found that a lot of uncertainty was generated when database updates were handled by several individuals using their own tools and methods to affect the required changes.  To remove this uncertainty, all database change must be executed using the same tools and processes across departments and individuals.   The tricky part: a continuous integration system has different requirements than a developer working iteratively or a DBA processing a batch of changes in a headless environment during a maintenance window.  In order to unify your database change process, the solution you use should be accessible to all of these individuals while maintaining the consistency of deployment activities.  That's why Datical DB provides a rich GUI experience for developers that helps them craft & deploy changes in dev environments; tight integrations with popular build and release automation frameworks that preserve the frameworks' workflows while providing Datical DB functionality; and a command line interface that allows users in headless environments to deploy changes in the exact same manner that the GUI or a 3rd-party integration would.  By unifying the modes of delivery you are constantly testing your release practices. By the time the production push rolls around, your system works.

Whether you develop apps or manage business critical apps that help fuel your business, what happens when users experience sluggish performance? You and all technical teams across the organization – application, network, operations, among others, as well as, those outside the organization, like ISPs and third-party providers – are called in to solve the problem.
Information technology is an industry that has always experienced change, and the dramatic change sweeping across the industry today could not be truthfully described as the first time we've seen such widespread change impacting customer investments. However, the rate of the change, and the potential outcomes from today's digital transformation has the distinct potential to separate the industry into two camps: Organizations that see the change coming, embrace it, and successful leverage it; and on the other side, organizations that will find themselves as roadkill on the technology highway.

Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?

19th Cloud Expo, taking place November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA, will feature technical sessions from a rock star conference faculty and the leading industry players in the world. Cloud computing is now being embraced by a majority of enterprises of all sizes. Yesterday's debate about public vs. private has transformed into the reality of hybrid cloud: a recent survey shows that 74% of enterprises have a hybrid cloud strategy. Meanwhile, 94% of enterprises are using some form of XaaS – software, platform, and infrastructure as a service.
DevOps and microservices are permeating software engineering teams broadly, whether these teams are in pure software shops but happen to run a business, such Uber and Airbnb, or in companies that rely heavily on software to run more traditional business, such as financial firms or high-end manufacturers. Microservices and DevOps have created software development and therefore business speed and agility benefits, but they have also created problems; specifically, they have created software security issues.
Between the mockups and specs produced by analysts, and resulting applications built by developers, there exists a gulf where projects fail, costs spiral, and applications disappoint.

Deploying applications in hybrid cloud environments is hard work. Your team spends most of the time maintaining your infrastructure, configuring dev/test and production environments, and deploying applications across environments – which can be both time consuming and error prone. But what if you could automate provisioning and deployment to deliver error free environments faster? What could you do with your free time?
