ארגונים ברחבי העולם מגבירים את השימוש בתהליכי DevOps לטובת שיפור היתרון התחרותי שלהם, הורדת סיכונים והפחתת עלויות פיתוח. כיום ניתן ליישם את ההצלחה של ה-DevOps בעולם מסדי הנתונים, על ידי ביצוע אוטומציה של תהליכי הפיתוח והעברה בין סביבות, אכיפת מנגנוני אבטחה, והפחתת הסיכונים הכרוכים בתהליך.

14. Why Continuous Delivery?

15. 15
But…
what about the database?

16. Only 13% are actually performing basic CD practices for the DB!!!
Manual work:
cant scale, cant match CD frequency
not repeatable, prone to error
Continuous Delivery is big and getting bigger, but...

17. Manual steps lead to Chaos in Emergency Times
90%
Rate this as a risk factor, but
53%
Break the process and test urgent hot-fixes in pre-
production

18.  Old adage but true
– The database is often neglected and therefore can become the
weakest link
– Manual processes
 Database/Code Silos exist…
– Don’t always communicate effectively
– Need to follow same procedures & best practices
 Essential from a compliance and business point of view
 Should be the strongest link
Is the database the Weakest link in a chain ???

19. The Database is a constraint

20. Only 13% automate…
the rest do manual steps…

21. What is the problem?
▪ Root Causes for issues:
− Challenging manual source control process
− Static deployments code overrides and configuration drift
− Dynamic deployments tools unaware of version control
− No release automation red-flags – don’t know when to stop the line…

22. File Version Control Process

Version control is out of sync from the database and cannot act as
a Single Source of Truth

23. 90%Rate this as a risk factor, yet
72%Admit database may not be in sync with the source repository

24. ▪ Challenges:
￭ Code-overrides
￭ Working on the wrong revisions
￭ Scripts do not always find their way to the version control solution
￭ Out of process updates go unnoticed
￭ Hard to locate outdated update scripts
▪ Playing safe? What we really need:
￭ The upgrade script
￭ The actual code of the object
￭ A roll-back script
Scripts & version control

Challenge with static scripts…
Configuration drift…

26. 60%Of those manually building scripts have to fix or tweak them regularly as part of a deployment process

27. 80%
Rate this as a risk factor, yet
71%
Follow manual processes to create their database deploy scripts

28. ▪ Scripts
− Hard to test in their entirely (holistically)
− Hard to test due to colliding dependencies
− Need to run in a specific order…
− Much harder to deal with project scope changes
▪ Scripts, unless super sophisticated:
− Unaware of changes made in the target environment
− Time passed from their coding to the time they are run
− Potentially overriding production hot-fixes or work done in parallel by another team
Scripts are static…

29. Test cases using compare & sync tools:
An index exists in source (QA) but not in target (Production)
What should we do? Add the index or not?
Using tools

30. Safe to automate?
Sure… (?)
Challenge with ‘Compare & Sync’

31. Safe to automate?
No. Requires manual inspection…
Challenge with ‘Compare & Sync’

32. 70%of those using compare & sync tools have to review and fix the results as they can't always trust them to automatically deploy
correctly

33. A compare & sync tool:
▪ Is unaware of any changes that occurred before the time it ran
▪ Has no knowledge of changes that took place at the target environment
▪ Does not leverage version control for more information
▪ Unable to deal with conflicts & merges between different teams
▪ Requires manual inspection
▪ Requires detailed knowledge regarding
each change as part of the process
So…no automation…
We fear for automating problems into
production and a major risk!!!

￭ Support out-of-process changes
￭ Utilize baseline aware analysis

40. If we had the index in the baseline (previous version) and no longer in Dev (i.e. - removed)
=> we should take it down from production…

42. Dealing with conflicts => merging changes

43. Conflict Resolving – Meta Data/Content

44. Continuous Delivery Pipeline Builder
• Define a process
• Automate the process
• Prevent/Alert out of process changes

45. Raise red flags to stop the line…
if requires human intervention
Impact Analysis! Not Damage Control…

46.  Automate “everything”
– Package the deployment of database changes along with all your other
application components to give a unified picture
 Move the process upstream
– Easily promote the same package (including database changes!) from one
environment to the next, handling environment-specific differences automatically
 Create the deployment pipeline
For successful CD:

47. ▪ Requited integrations into entire continuous delivery pipeline:
￭ IDEs (Oracle, Microsoft, MySQL in dev)
￭ Source control (MsTFS, Git, Subversion etc.)
￭ Task based development and ticketing systems (Jira, MsTFS, IBM RTC
etc.)
￭ Build tools (Jenkins, bamboo etc.)
￭ ARA tools (IBM uDeploy, CA release automation, Chef etc.)
Integrated CD world…

48. ▪ Focusing on changes rather than managing changes and
dealing with re-work, boosted overall productivity of 250
developers. We estimate we were able to do 15% more with the
same resources.
▪We went from several fix-centric deployments a day, to one
feature-centric deployment a week.
▪The amount of incidents in production has declined as well. We
had 20% less incidents.

49. ▪ Regulation requirement - SOX and derived 357
▪Auditing - change management approach with change
management auditing. You have to do it anyway, do it
automatically and efficiently.
▪Change management in production itself is regulatory
required (ITIL). But you cannot ensure it without managing
the whole process starting at Dev.
▪We have to comply with regulation - but the business
benefits from it.
