Continuous
integration and delivery is an effective method for pushing code changes to
development as quickly as possible. It will help your team cut down mean time
to resolution, avoid issues in code integration and ensure that essential fixes
reach customers quickly.
However,
the nature of CI/CD also creates significant room for error. Because code is
being continually integrated into a larger code base and staged for deployment,
the method can take a lot of effort to maintain.
Here
are five tips your organization can use to optimize its CI/CD pipeline.
1. Track the
Metrics That Matter
The
right metrics will act as a key performance indicator for your
CI/CD. Cycle time, mean time between failures and mean time to recover are
three commonly-tracked CI metrics and an excellent
place to start. Following these numbers will help you track the efficiency of
your pipeline over time. Long cycle times, for example, can reveal considerable
dead times and inefficiencies that you may be able to manage with parallel
builds or by running unit tests.
2. Coordinate
Integration and Delivery
Code
should be passed off and moved down the pipeline without the need for major
discussion or indecision. For effective CI/CD, devs, QA and other staff members
must know exactly what their responsibilities are, and who they should deliver
code to once they've played their part.
If
your CI/CD pipeline isn't entirely in the cloud - which is likely, as just 39 percent of organizations plan on having the
bulk of their data and software on the cloud by 2020 - massive amounts of
data or code may need to move from local storage to the cloud or vice versa.
This
process will require effective automation and excellent communication between
team members and structures that help facilitate coordination. These structures
and relationships won't necessarily be easy to build, but they will help ensure
that the CI/CD pipeline is highly efficient once established.
3.
Practice Regular Logging
If
code fails a test during the delivery process, exhaustive logging will be the
best way to isolate and identify the cause of the failure.
Your
team will need to balance logging against performance, as logging can quickly
get resource-intensive. An advanced logging framework that adjusts the amount
of information being logged - depending on triggered flags for certain failure
events, for example - can help your team manage resource use while still
recovering essential information.
4. Approach
Automation Incrementally
Moving
from manual processes to automated ones can be tricky business. Often,
companies that pivot to using a CI/CD pipeline don't know where to start with
automation.
The
best place to start with test automation is by finding ways to save your
team the most time possible. Tests that your team runs frequently will make
better candidates for automation than the tests your team runs rarely, for
example. Tests that require specialized experience or knowledge are also
excellent, as you can ensure that they won't be bottlenecked by the
availability of a few developers or quality assurance specialists.
Once
you and your team are comfortable with this initial step, you can automate
additional tests, freeing up more time and speeding up the CI/CD pipeline.
5. Make Security a
Top Priority
A
CI/CD pipeline can create new security vulnerabilities. As a result,
your team may need to take a new approach if you want to keep your code
secure.
Many
workers, for example, don't have access to automated security testing tools,
which can significantly slow down the pipeline and make testing more cumbersome
than it needs to be.
Optimizing Your
CI/CD Pipeline
CI/CD
is a powerful approach for dev teams wanting to cut down on the time it takes
for an idea to reach production. However, CI/CD can also be hard to implement
well. Tracking the right metrics, logging extensively and making coordination
between team members a priority can go a long way toward optimization.
