DEVOPS CHALLENGES AND BEST PRACTICESHow to use tools and cloud services to improve deployments
THE VALUE OF THIS PRESENTATION
The pursuit for the perfect synchrony between software development and IT operations is still ongoing, and striking the balance won’t happen any time soon.
Understand and address these 5 common DevOps challenges to achieve a higher- functioning and collaborative organization.
5 CHALLENGES PLAGUING DEVOPS
CULTURE COMMUNICATION & PROCESSES INFRASTRUCTURE
TOOLS & APPS BUDGETING
CHALLENGE 1: CULTURE
STRUCTURAL CHALLENGE:
What happens to
traditional development and operations silos?
ACCOUNTABILITYCHALLENGE:
Who owns it?
Culture exists no matter what, and it usually creates itself. A frictionless process and the ability to scale only works when teams work as one.
CHALLENGE 2: OUTDATED COMMUNICATIONS AND PROCESSES
The bottom line: manual build and test processes increase errors.
It takes a long time to provision resources (obtain
testing tools, change servers)
- And -
Developers make frequent unique changes…
The quality of development and testing is
diluted.
Because…
CHALLENGE 3: OUTDATED INFRASTRUCTURE
Inflexible networks’ interdependency cant be changed, broken, moved or replicated.
IPs
Ports
Routing tables
No self service
Little to no automation
CHALLENGE 4: TOOLS & APPS
DEVELOPERS• Don’t have a holistic view of the
business• Don’t understand why a quick fix
tool won’t work• Use non-approved tools
BUSINESS USERS• Believe everything can be solved
with an app• Don’t understand the complexity
of backend integrations• Use non-approved tools
CHALLENGE 5: BUDGETING
CAPEX OPEX
Capital and operational expenses are tied together.

TIPS
• Create DevOps champions throughout the organization to distribute the workload of DevOps evangelism and DevOps implementation
• Select a single champion to own creating a collaborative environment

TIPS
• You need a champion for this endeavor. If this is the CIO, he/she must be a planner and a manager, not just the technician in chief
• Must create collaborative environment
• Shift focus from individual department to interdepartmental collaborative teams

SOLUTIONS
Bridge the culture gap
A key performance indicator (KPI) is a business metric used to evaluate factors that are crucial to the success of an organization.
Evaluate KPIs TIPS
• Track metrics that look at systems as a whole, not siloed information
• Don’t let KPIs conflict with agility and customer
satisfaction
• Look at KPIs that tell you how your automation processes are improving the overall delivery capabilities: frequency of builds, build success rates, build time
When team members become more poly-skilled and silos are dismantled, communication is improved, and bottlenecks are removed from old-world software organizations. 3
SOLUTIONS
Bridge the culture gap
TIPS
• Let your team’s skill sets evolve
• Encourage developers and operations to share responsibilities.
• Create shared incentives
Spread the wealth
SOLUTIONS
Bridge the culture gap
When team members become more poly-skilled and silos are dismantled, communication is improved, and bottlenecks are removed from old-world software organizations.
Share success
TIPS
• Use internal corporate social outlets to help drive efficiency and productivity and enhance traditional tools like IM, email, and service desks
For DevOps to succeed, team-to-team communication, transparency, spread of knowledge and fast feedback loops are essential.

When team members become more poly-skilled and silos are dismantled, communication is improved, and bottlenecks are removed from old-world software organizations.
TIPS
• Create an open and honest environment where it’s ok to make mistakes
• Encourage “blameless” post-mortems
• Implement version control
• Transparency through tools
Promote transparency5
Ability to use a wide variety of open source technologies and tools Ability to code and script
Experience with systems and IT operations Comfort with with frequent, incremental code testing and deployment
Strong grasp of automation tools Data management skills
A strong focus on business outcomes Comfort with collaboration, open communication and reaching across functional borders

SOLUTIONS
Bridge the culture gap
TIPS
• Because resources are hard to find, teach high-performing internal personnel
• Look for individuals that know how to build the tools that remove pain points instead of experts in a particular software
• Recruit and retain women. Strive for a diverse group.
Only 18% of people have a DevOps title.

There is no one size fits all tool set. You must analyze your business requirements, your IT group, your budget, your legacy systems and workflows.

SOLUTIONS
Bridge the culture gap
Identify the right tools
Encourage self-service.
It’s efficient and cost effective.
Prior to 1916, if you went into a grocery store, you would have to present a list of the things that you wanted to buy to a store employee. The store employee would then escort you
around the store and gather the required items for you.
Piggly Wiggly Store: In 1916, Clarence Saunders changed all this when he invited his customers to gather the items they wanted themselves and present them to a cashier. This was so revolutionary that in 1917 the US patent office awarded him a patent for his "self-
service store". This spawned a chain of now 600 Piggly Wiggly self-service grocery stores.

SOLUTIONS
Bridge the culture gap
Identify the right tools
TIPS
• Ask the right questions of the tool providers
• Is it OS restricted? • Does it support the application platform we need to
support? • Can I extend capabilities via custom scripts? • How much infrastructure needs to be in place before I
can start using it? • Is it Agent Based, Agentless, or a Hybrid? • Does the tool have a Domain Specific Language or does
it use a standard method for describing work to be done?
Implement a configuration
management tool

application deployment tool
TIPS
• Find a tool that tracks behavior—from history to change logs–in ways that is meaningful for both dev and ops.
• Make sure that the application deployment tool you pick is compatible with your configuration management tool

monitoring tool
TIPS
• Select tools that fit the culture, avoid trying to force culture to fit a specific tool.
• Look at every aspect of a business transaction – starting from the user experience, the application performance, how the application interacts with the infrastructure, and then finally what is the business impact and how is the business performing.

Born out of trying to find a better way to execute projects, DevOps relies on the foundation of agile to improve project execution and deployment and synergy.
• Agile makes the most of the improved feedback from DevOps (increases the value of DevOps)
• The quicker development of features improves buy-in to DevOps from operations personnel (Users get better tools quickly from their feedback)
No plan of operations extends with any certainty beyond the first contact with the
main hostile force.

Worse, Iridium’s cell phone couldn’t make calls from cars, offices or other buildings since phones had to be used outdoors with a line-of-sight connection to the satellites. But the nail in the coffin was price. Instead of the 50
cents per minute for a regular cell phone, Iridium’s calls cost $7 per minute–
What happens without
continuous feedback?
The Iridium Phone Fail:
• 11 years concept to launch• Heavy• Inconvenient: Couldn’t make calls from cars,
offices or other buildings• Pricy: instead of the 50 cents per minute for a
regular cell phone, Iridium’s calls cost $7 per minute
The company burned its way through more than $5.2-billion because it fell in love with technology, succumbed to Waterfall product development and never bothered to ask, “What do customers want today?”

TIPS
• Understand how the cost model changes affect accounting
• Don’t be afraid to look for money in business budgets
• Understand that there is upfront spend.• Consider cost vs. value: FinOps• Leverage cloud solutions like Azure or
AWS to lower the required OpEx and CapEx
