Welcome back. In this lecture, we'll introduce you to Atlassian Bitbucket and how it can be used to manage, maintain, and vision control your own source code using Git. We'll highlight many of its core features and later on, follow up with a series of hands-on demonstrations. This lecture is all about familiarizing yourself with the Atlassian Bitbucket cloud-hosted service ensuring you know when and where to use it within your own software projects. Okay, let's begin. For this course, we're focusing on Atlassian's BitBucket Cloud-hosted version. Alternate versions of Atlassian BitBucket do exist, allowing it to be installed on prime. 

As just mentioned, Atlassian BitBucket is provided in multiple versions using a freemium pricing strategy. For starters, you can get going with BitBucket free of charge, where its entry-level free version is positioned at small teams, providing up to five users for collaboration per repo, unlimited private repos, doer integration, and limited to 50 minutes of automated Build time per month for its pipelines feature. Additionally, you also get one gig of file storage for LFS. LFS being Large File Support. The next licensing option up from free is Standard, suited to medium and growing sized teams, which is mainly differentiated from the free version by allowing unlimited users, but also increases the number of Build minutes per month from 50 to 500 for pipelines, and LFS increases from one gig to five gig. Finally, you have the Premium version suited to very large teams. The premium option introduces additional security mechanisms for enhanced control of your version-control workflows such as enforcement of merge-checks before merging and IP whitelisting. With Premium, the number of Build minutes per month caps out at 1,000 minutes and LFS caps out at 10 gig. 

Additionally, Premium comes with the ability to perform smart mirroring between Cloud-hosted BitBucket repos and on prime BitBucket repos. More on that later. Extra Build moments and or LFS storage can be purchased independently of the BitBucket plans, starting at $10 per month for an additional 1,000 Build minutes and $10 per month for an additional 100 gig of storage. As previously referred to, BitBucket can be hosted and licensed on prime. Supporting this approach is two different licensing options named Server and Data Center. The BitBucket Server license is strictly for a single node or single-server hosting the BitBucket software. The installation of BitBucket Server implies that the load capable is directly associated with the specs of the server onto which it has been installed. Any downtime of the one server will directly impact the ability to use BitBucket until such time the downtime has been resolved. Interestingly, you can purchase a self-hosted BitBucket server license for 10 users for a one-off payment of $10, which is priced at small teams to get them up and running. 

However, the next step up in terms of maximum users goes from 10 users to 25 users for $2,000 and then $3,600 for 50 users and onwards and upwards. The BitBucket Data Center license allows you to scale out and run a redundant cluster of servers onto which BitBucket is installed. Basically, you can run a fleet of servers that sit behind a load balancer and for which is seen by clients as a single logical instance of BitBucket. With this mode and set-up, your performance and availability of BitBucket are increased, allowing you to tolerate single node outages. Unlike the server license, the Data Center license allows you to perform smart mirroring between BitBucket cloud-hosted repositories and repositories hosted on prime. This improves the time to perform tasks such as cloning a large repository since now that can be done on the local network instead of over and across the internet. The pricing starting point for BitBucket Data Center is $1,800 for an annual license for 25 users, increasing as the number of users increases. Subscriptions can be purchased, either for 12 months, 24 months, or 36 months with discounts being applied if committing to a 36-month term. Okay, that completes this lecture on BitBucket licensing and pricing. Go ahead and close this lecture and we'll see you shortly in the next one.
