Audience Level Intermediate Synopsis In this presentation, Shunde will show you how to simplify the migration process with a workload migration engine, making the move to OpenStack easy. This talk will address the various difficulties operators and administrators face when migrating workloads and resources between various cloud platforms, including removing time consuming, repetitive and complicated steps. This tool can be applied to many cloud migrations, including between Virtual Machines and OpenStack, between Public and Private clouds, as well as between OpenStack and OpenStack. This tool integrates completely with other OpenStack projects minimising deployment and maintenance efforts. So whether you’re looking to upgrade from your existing traditional virtualisation platform, setup a new OpenStack instance, or upgrade to a newer version of OpenStack, we will show you how to simplify this process using GUTS. Speaker Bio Shunde is a senior software developer in Aptira with over 15 years experience in software development, automation and system administration. He has worked with OpenStack since the Diablo cycle and has been involved in projects from OpenStack infrastructure to distributed systems running on top of OpenStack.

5. Manually migrating existing
resources is difficult.

6. Cloud Migration
Difficulties
➔Moving from older, traditional
platforms is risky
➔Processes are repetitive and
complicated
➔There’s too much data to move
eg. machines running multiple virtual disks
➔Customised hypervisor specific
tools are running
➔Manually copying data is too
time consuming
Common Administrator Complaints

should be simple.

9. What is GUTS?
GUTS is a Workload Migration
Engine designed to automatically
move existing workloads and virtual
machines from various
virtualization platforms on to
OpenStack.

10. GUTS
Migrates...
Workloads between:
Traditional Virtualization
Platforms ↔ OpenStack
Public ↔ Private Cloud
OpenStack ↔ Openstack

11. GUTS can migrate computing
instances from Traditional
Virtualization Platforms like
VMware, AWS, Hyper-V, etc to
OpenStack.
VM’s
OpenStack

12. Public Cloud
Private Cloud
GUTS facilitates the migration of
resources and customer
applications between public clouds
and private clouds.
(such as AWS to OpenStack)

13. OpenStack
OpenStack
GUTS can be used to migrate
resources from one OpenStack
Cloud to another.

14. Cloud Upgrades
&
Maintenance
GUTS supports:
- Icehouse
- Juno
- Kilo
- Mitaka
- Newton
- Ocata and continuous...

15. Complete
Environment
Migration
GUTS can also be used for
complete cloud environment
migrations including users, tenants,
security groups, keypairs, flavors,
networks, volumes and instances.
OpenStack ↔ OpenStack

16. Migration
of User
Applications
GUTS can also migrate end user /
customer applications between
clouds.

17. The missing piece to the
migration puzzle
Distributed + Interactive + Synchronous + Pluggable

18. Distributed
GUTS contains three internal
daemons (guts-api, guts-scheduler
and guts-migration), which
communicate through RPC.

19. Interactive GUTS interacts with source and
destination clouds through RESTFul
APIs during the migration process.

20. Synchronous
Using GUTS we can perform 1 to
100s of migrations at a time.
GUTS maintains locks on shared
resources.

21. Pluggable
GUTS follows the pluggable
architecture, allowing cloud
operators to add support for new
cloud platforms.
