Question 1. What Is The Definition Of Continuous Integration And Continuous Deployment For You And The Company?
Continuous Integration is testing your code all of the time and preserving software nice high. It offers you the confidence to get stuff out as fast and frequently as possible
Continuous Deployment is largely getting code into manufacturing. Things must be easy and repeatable. That’s wherein Continuous Deployment comes into play. Deployment have to no longer be manual.
Question 2. Was Continuous Deployment Planned And Used From The Beginning At Grabcad?
In the start we used Engine Yard for deployment. Over time we used extra Scala and Java in our functions. This was no longer supported as well as wanted so we moved to AWS and placed more emphasis on automation throughout the infrastructure.
We have about 30 production servers in place right now. You devote your code and if it passes all the assessments it'll make its manner into production thru our computerized machine.

Question 3. Could You Explain Your Workflow? What’s Your Sprint Length, Ticketing?
We do Scrum with 1 week sprints. We do our dash planning at the beginning of the dash (which does no longer need to be aligned with the beginning of the week). Then the team starts to work on the functions which have been agreed upon. Every function this is accomplished gets into production. The feature groups decide on their very own how lots wishes to be tested for that function. Sometimes we push to a staging surroundings.
When a function is ready you merge to master and then visit Jenkins and push the “OK DEPLOY” button. We launch a couple of times an afternoon.
After the week we do a sprint overview.
Question four. How Do You Do Release Planning?
Once a quarter we do release making plans. The first week or two of the quarter is for planning the quarter and then we have about eight to 9 weeks we are able to paintings at the capabilities.
For the initial backlog we do difficult estimations. We calculate in factors. We study factors and notice: “This crew has approximately six hundred factors left and we realize how much the team can still do.”

Question 5. Who Defines The Goals?
Goals come from the organization degree. The dreams then get cut up up into duties and functions. We attempt to cut up them up in as small pieces as feasible so we are able to get them into the sprints efficiently. We also do a semi-particular breakdown with the aforementioned factors (e.G. 2 hundred factors for this selection)

Question 6. Which Metrics Are You Using To Determine The Work Within Your Teams?
It’s no longer clean to define significant metrics for the engineering groups.
Take this example:
A feature is prepared and live. But then the advertising and marketing promotes it and the whole thing else kicks in later. You can validate the end result of the function handiest afterward. The engineering crew’s aim is to supply the characteristic.
Our KPIs for engineering are:
speed (scrum points),
quantity of deployments to production in line with week and
variety of regressions in keeping with characteristic/developer.
This gives us self belief in Continuous Deployment.
The sales crew’s metrics include:
engagement and others
Question 7. Your Team Works In Three Locations. How Does That Work For You?
The development groups are pretty flippantly spread during 3 nations. Having anybody in a single location has much less overhead in verbal exchange but because of occasions we had to have three locations.
However, having small groups has plenty of benefits and might atone for geographical gaps. For example you may easily see in which something went wrong and take short action against any mishappenings.

Question eight. What’s The Team-composition At The Different Locations?
We have groups in Estonia, the United Kingdom and within the USA. We moved faraway from very purposeful groups in different locations to go-purposeful teams in all locations.
We do have specialised groups owning distinct sections of the product though. If all people owns the whole thing, no-one owns nothing.
We do shift our groups every so-often to keep them fresh or while we've a new project and spot that a specific person is perfect for that mission.
Question 9. How Did The Team Grow Over The Times?
The center of the employer began in Estonia and the CEO moved to Boston. Our biggest marketplace is inside the USA. Today we have the headquarters, the product control groups and the income teams within the USA.
We were also able to land key CAD specialists inside the UK which triggered beginning the 0.33 place.

Question 10. What Do You Use For Product Management?
We now use JIRA and GreenHopper. Originally we used AgileZen.
Question 11. When Do New Developers Get Productive In A New Team?
They can commit to the work inside the first week.

Question 12. What Do You Think Will Get You More Productive In The Future?
We want to make the staging and Continuous Deployment and Testing environment higher. These things are massively critical for development productivity. We are putting a whole lot of attempt into it on this region.
We also are thinking about converting to one-of-a-kind languages. In Rails some overall performance and preservation responsibilities aren't as we love them to be. We may additionally trade some things to Scala or Java to get better overall performance.

Question 13. Which Strategies Do You Use To Test Or Measure The Performance Of Your Application? Think Load Testing Vs. Monitoring.?
Currently we don’t do loads of load testing. We might do it inside the future. We use New Relic and our very own monitoring. The GrabCAD website grew organically. We have a regular boom pattern now and its pretty smooth to estimate what’s going to appear inside the close to future.
Question 14. How Do You Grow And Scale Your Application?
We are on and want to live with cloud providers. Cloud services are totally well worth it. Think about IT people, servers, cooling systems and plenty of extra. There are loads of hidden prices you save while you use cloud offerings.
Question 15. Have You Built Your Own Management Tools On Top Of Amazon Or Do You Use A Lot Of Amazon Providers?
We have some basic scripts. We are the usage of Chef. Amazon instances provide a Chef purchaser. It’s really clean to create the machines and it’s comfortable.
Getting something like this in place is paintings extensive and you have to figure out if it’s worth some time inside the early days. We deliberate quite a few overhead to apply Chef and built this setup.
We pay far less for our servers than for our office and salaries, so it’s now not an problem. If we need to cut charges we simply must improve our code base.

Question 16. What Is Continuous Integration?
Continuous Integration may be defined as “Building software and taking it through as many checks as feasible with each trade”.
Question 17. Why Is Continuous Integration Important?
Two essential motives:
Defects located early cost less to restore : When a disorder is discovered at once after a developer codes it, it takes 10x instances much less time to restore it in comparison to finding the defect a month later.
Reduced Time to Market : Software is usually tested. So, it's miles constantly prepared to transport to further environments.

Question 18. How Is Continuous Integration Implemented?
Different equipment for helping Continuous Integration are Hudson, Jenkins and Bamboo. Jenkins is the most famous one currently. They provide integration with various model manipulate structures and construct gear.

Question 19. What Are The Success Factors For Continuous Integration?
Implementing the gear for Continuous Integration is the clean part. Making excellent use of Continuous Integration is the complex bit.
Question 20. How Often Is Code Committed?
If code is committed as soon as an afternoon or week, the CI setup is below utilised. Defeats the cause of CI.

Question 21. What Steps Are In Continuous Integration?
More steps in continuous integration manner greater stability.
Code Quality Gates
More steps in non-stop integration may make it take greater time but consequences in extra solid application. A change-off needs to be made.
Run Steps a,b,c on a devote.
Run Steps d & e as soon as every three hours.
Question 22. How Long Does A Continuous Integration Build Run For?
One choice to lessen time taken and make certain we have immediate comments is to cut up the lengthy running assessments into a separate construct which runs much less regularly.
