The Linux Foundation Collaboration Summit in February 2015 featured discussions on cloud computing and microservices from industry experts. Key topics included the evolution of cloud technologies, the importance of open-source solutions, and challenges in managing distributed systems and services. The summit emphasized collaborative innovation and the shift towards microservices and declarative architectures in software development.

Low resource efficiency Containers Hermetically sealed deployment units Efficient isolation and resource use. Clustering Declarative app model Agile, decoupled architecture Smart (Machine Learning Enhanced) Active Management New World - Cluster First Development Radically enhanced developer productivity: snap together systems. Radically reduced operations overhead: deploy, run, update effortlessly Operational specialization: cluster/infra ops separate from app ops

- 36. microservices(n) - Loosely coupled service oriented architecture with bounded contexts If every service has to be updated at the same time it’s not loosely coupled If you have to know too much about surrounding services you don’t have a bounded context.
- 37. • Microservices can be introduced quickly • Leave old services in production until time to clean-up • Allows for faster speed of innovation • Code pushes are only additive so no legacy issues

- 40. Alex Williams (the New Stack) : Looking out at 2015, what are some of the issues that will be more complex in this distributed infrastructure world for customers – what are some of the top ones you see? Mitchell Hashimoto(Hashicorp) - Number one is service proliferation, where your data center just becomes more and more services. Number two is, inherently becoming multi-data-center and highly-distributed at a much earlier stage. With things like Docker, where you can run things in much smaller units, it becomes a lot easier to start running a lot more services. As a result, we have a management problem, an orchestration problem, and distributed system problems in there.

Editor's Notes
- #3: My name is Mark Hinkle and I work on open source at Citrix. We are active in the Apache CloudStack Cloud Computing Community. (www.cloudstack.org) The Linux Foundation’s Xen Project (the open source hypervisor) and Open Daylight projects. (www.xenproject.org and www.opendaylight.org) We also operate XenServer as an open source project as well. (www.xenserver.org) I don’t do what I do because I want to sell software. I do what I do because I believe that what I do helps make the world a better place. Because I help make the world a better place it helps my employer make money. Win-Win-Win.

- #33: Flocker Documentation - https://docs.clusterhq.com/en/0.3.2/introduction.html#motivation-for-building-flocker Flocker lets you move your Docker containers and their data together between Linux hosts. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app. Even stateless apps depend on many stateful services and currently running these services in Docker containers in production is nearly impossible. Flocker aims to solve this problem by providing an orchestration framework that allows you to port both your stateful and stateless containers between environments.

- #45: How many people here use VMware? How many people use Hyper-V for virtualization? How many people benefit from joint collaboration between VMware and Micrsoft on those technologies. How many people here use Red Hat Linux? Keep your hands up. How many people here use Ubuntu Linux? Keep your hands up. How many people here use Debian Linux? Keep your hands up. How many people use some an Android device? Keep your hands up. How many people use a Rasperry Pi or some other embedded device? Keep your hands up. How many people benefit from joint development of the Linux kernel? Everyone who has their hands up should keep them up. The difference between proprietary software and open source is that if you go down the proprietary road it’s rare that your contributions can help the users of another project be successful. In open source that’s par for the course. Sometimes we get competitive on who has the best open source project. I liken this to fraternities at a college but in the end we all cheer for the same football team on Saturday. Together we all win. I work on Xen Project and XenServer and we rely on QEMU, so does KVM both communities benefit from that upstream both communities help contribute back feedback that makes QEMU better. I work on Apache CloudStack and we work with Ceph, Gluster, Scalr, Puppet, Chef, Zenoss, Riak CS, Xen, KVM, Open vSwithc to integrate their technologies and give feedback to make them better. Lot’s of you work on OpenStack. Both projects contribute to a broader ecosystem that is better for everyone.
