Discovering and addressing the extras needed beyond the selection of a provider is often overlooked when launching a new product to the cloud. Among the many areas to research are security and compliance tools, centralized monitoring and log aggregation, utilities for backups and snapshots, and anything that automates rote housekeeping. As soon as discovery begins, these are some of the common questions that arise:
A common first step is to search the web with a phrase like “Cloud Configuration Management Tools” and begin parsing the results. However, this immediately presents some challenges: Google returns nearly a million results, Bing nearly three million, and so on. The first page of results will undoubtedly have one or two “Top 10” this or “Top 25” that, but often these lists do not provide any clarity towards selection. In fact, the tendency becomes to either hunt through all the results until a particular post or documented use case appears to be a match or, frequently, use an existing vendor relationship to see if any of their offerings may fit the need. While either option could have a positive result, a fast, lightweight process with both rigor and flexibility is more likely to yield true benefit.
When faced with a critical need and many options, the best place to start is a list of concise, prioritized requirements. Start with the criteria underlying the drivers for a configuration management tool: environment control, audit mechanisms, task automation, etc. If possible, have another stakeholder review them and provide feedback. Repeat with the ideal response for a product meeting the criteria such as “able to provide immediate 30 day view of all configuration changes with time, date, user, workflow, delta, result” etc. These inputs will form the basis of structured analysis of any potential offering.
As a general rule, ignoring the millions of search results will be a good first step when selecting a vendor product. Using a trusted research team, like our own Levvel Research, will give you a superior view of the market leaders to consider.
Plus, most providers provide insight into their own preferences through blogs and how-tos. In the case of Cloud Configuration Management, keep the focus on vendors’ products which readily extend the capabilities of your provider(s). Also consider the trajectory of your provider(s) relative to their peers—the responses from a vendor may depend on their investment of time and attention to each, often based in turn on the expectations for exposure and revenue growth.
In the Cloud Configuration Management use case, vendors of all sorts and sizes cover the field. Many are tied to their respective providers e.g. Amazon OpsWorks, Azure Automation DSC, and Google Deployment Manager, while others, such as Platform9 and Google Anthos, are more agnostic. Provider offerings can always be considered, but agnostic options can provide additional flexibility, independence, and an easier path to implementation. Levvel helps narrow the field by applying our industry expertise to your requirements and identifying the best options for you to evaluate.
Now for the fun part—making the choice.
Pull up the requirements and success criteria from the discovery process during Research and incorporate them into an updated comparison chart format. The key here is a balance between covering all bases and remaining nimble—keep the focus on core functionality of configuration management. As a general rule, restrict the list of requirements/criteria to roughly ~30 items to prevent input fatigue and avoid watering down the evaluation.
Next, consider utilizing the flexibility and depth of a scoring matrix to evaluate the capabilities, posture, and trajectory of a vendor and their product. For example:
Note the opportunity for differential feedback from those involved in selection. Instead of simple Yes/No answers against criteria, objective and subjective analysis converges to achieve clear insight to a vendor’s suitability. Levvel provides additional insight into which questions to ask, how to rank their importance, and how to evaluate the results against the needs of your product or organization.
A couple of notes on this part of the process are relevant:
Also, remain objective and wary of confirmation bias as feedback is assessed and scoring for the finalist (or finalists) is prepared. When presented with two or three solid options and/or your organization prefers process-driven selection, this may result in the need for committing to an RFI/RFP which is outside the scope of this document. However, it should be noted that the tools and guidelines above are relevant to that process, especially the collection and evaluation of criteria using both objective and subjective analysis.
To promote a constructive, productive approach when implementing a new tool, consider a disciplined review of the basics: the vendor’s typical introduction and first-run documentation, any available GitHub repos, FAQs/KBs involving other customer deployments, and getting a sandbox implementation up and running. The sandbox is essential for giving your teams a chance for early and regular access to a Configuration Management solution supporting:
Per the first item above, do not undervalue the importance of mapping all your intended target systems and processes when identifying standards and crafting processes. For example, the most carefully-written deployment specification cannot overcome a missing object label, a misnamed container, or a keystore without the right client key. Comprehensive support for Infrastructure as Code (IaC) and Configuration as Code (CaC) is an essential characteristic to help address these and other similar scenarios.
Take the opportunity to draft and ratify documents for any standards you need such as server naming conventions, file system locations for configurable items, when to use datastores for configuration, and even a process for introducing change to standards.
Iteration through use cases and observing the interaction with other systems and processes will bring a tool’s eccentricities and behaviors into view. Collect and enact as many use cases as feasible to explore in the sandbox, giving each at least one end-to-end cycle. This is also an optimal time to approach the vendor with any questions or issues, remembering the classic adage “there is no excuse for poor planning, nor does it constitute an emergency for anyone other than the planner.”
At this stage, all of the pieces are in play: a product, a plan, and a playground. All that remains is the final “P”, Production. Everything up to this point is an exercise in exploring and learning, but the real proof is what happens when users start to interact with the product and systems start to depend on it for second-by-second operation. Some precautionary steps can help make the transition to pProduction easy to digest, among them:
With each step, consider recording the inputs and outputs into a documentation repository for reference when building tool and process documentation, an oft-overlooked step which can introduce operational gaps in the future. Having a concise, comprehensive view of how an environment is built and controlled can be just as valuable as a diagram of what exists and where. This is of particular importance in regulated industries where the ability to both demonstrate and provide evidence technology infrastructure controls are often audited.
While this guide may not apply to every vendor or scenario, the process and decision tools can provide the structure and consideration to select a tool which will grow along with products and services deployed in your cloud. Setting aside the time and resources to do the research, perform the analysis, and run some deployment iterations will reap considerable reward when production implementation begins.
