Introduction & Description of Talk:

Today's world is multi-cloud: in a recent 2018 study, 81 percent of enterprises respondent confirmed they had a multi-cloud strategy (Flexera Blog: https://bit.ly/2EGVZwH). One can only assume these multi-cloud strategies come from the fear of vendor lock-in: in July 2017, a study found that vendor lock-in was a concern for 80% of enterprises (Stratoscale Study: https://bit.ly/2J9Ys1j).

For engineers and sysadmins, multi-cloud strategies usually imply complexity: multiple APIs, multiple endpoints, and opaque workflows. Hence why Scality made Zenko (http://www.zenko.io), the free open source Multi-Cloud Data Controller. Zenko is a modular stack of microservices, that leverages Kubernetes for seamless deployment and management.

Zenko gives you the freedom to manage your data across all the main public clouds (currently: AWS S3, MS Azure, Google Cloud Platform, Digital Ocean Spaces, Wasabi; upcoming: Backblaze B2) and private clouds (Scality RING, local (privately hosted) S3 buckets, and soon Ceph RADOS) using a single endpoint (of your choice), and a single API: the S3 API. Zenko also lets you replicate across all these backends, and do metadata search across all of them. Practically, this means you get a single namespace across all of your backends. As if that wasn't enough, Zenko also comes with a web management UI, Orbit, that lets even the least technical of us set up replication across their storage infrastructure(s).

Finally, Zenko writes everything in native format, committing to giving you and your data freedom: Zenko is not a restrictive gateway: once you used it to write your data using the S3 protocol to any cloud, you may access / transform / read / get that data with any tool compatible with the backend you wrote to (including tools native to that backend).

This talk will assess the current state of multi-cloud, the enterprises need for more transparency on how their data is managed, and the solutions brought to them by Zenko, a free open-source stack of microservices that scales up to petabyte-scale for multi-cloud storage. The talk will include a live demo.

Addison-Wesley Professional/Prentice Hall PTR/Pearson, and O'Reilly have been kind enough to provide us with review copies of some of their books, which we will continue to raffle off as giveaways at our meetings. The publishers always ask that the persons receiving the books provide a review and/or feedback about their books.

Unigroup would like to thank both publishing companies for the support provided by their User Group programs.

As always, all of the books will be available for review at the start of the meeting.

         additional proof of current enrollment.  Thanks.
