2 Welcome! (about me?)

3 Background: Datalounges Decades of Multinational Corporate IT in experience Frustrated with vendor offering and sales tactics with lock-in Surveyed medium large ( employees) Enterprises about current Cloud offering and expectations / preferences Catering Enterprise: a whole new level of pain with HUGE rewards (not monetary).

4 Todays Hosting Market Many Cloud vendors, all the same product vserver cheap at first glance, hidden costs ridiculous, example: Azure, Amazon, Digital Ocean Same business model for small businesses, quick servers, not easily adjustable for enterprise. Enterprise = budgeting, budgeting!= flexible costs, Vendor approach is: Go in on small budget and speed, make customer adjust to us. Overselling in some cases is not anymore based on efficiency but on cash raking. Ratios of CPU 24-32/1 almost the norm with large vendors, some vendors go as high as CPU 48-64/1 RAM overselling the norm at a ratio of 2:1, sometimes 4:1 (swapping)

5 Openstack (SUSE Cloud) for the enterprise, ready or not Positives: Short answer: yes mostly Openstack provides flexibility, reliability and elasticity Opensource, a proper governance and the growth potential makes Openstack one of the most ideal OS Products for Enterprise. Ready distributions provide Enterprise with support options and management The concept for the user/customer to forget the hardware layer completely and be able to spin up VMs based on quotas is very appealing.

6 Openstack for the enterprise, ready or not Challenges: Pure Openstack is NOT easy to maintain Monitoring Openstack is non-existent (DIY or a combination of many tools, NONE of which is properly documented) To be effective and reliable, Openstack requires a good selection of hardware before hosting a VM can even start. In-house proof of concepts are quite difficult and require a steep learning curve (Time).

7 SUSE Cloud 5, reasons behind the choice Enterprise offering with Enterprise support Ease of maintaining and deployment of new resources (Crowbar) Well documented setup SAP and Microsoft support SLES -> broad support on horizontal level -> flexibility for customers Multi-Hypervisor support out of the box Driver Support for Windows Designed for large environments requiring flexibility

8 Infrastructure Design: Hardware Blade servers in Multiple Blade Centers Rack Servers for additional storage Storage over Fibre-channel and multiple 10gbE channels 10gbit Ethernet for Blades for fast deployment Multiple gigabit Internet interfaces Storage resiliency guaranteed by multiple channels

9 Infrastructure Design: Software SUSE Cloud with SUSE Manager for Patch deployment and maintenance CePH Storage backend with Glance and Cinder interfacing with it Customised Openstack Dashboard (why re-invent the wheel) LBaaS, VPNaaS - Site to site and via customised Strongswan appliance for remote access Project/Customer Environment approach, transparently granting access via VPN tunnels to own environments Full Console access to server,windows 2008, R2, 2012, 2012R2 support and image deployment Images for deployment include: SLES (11 and 12), OpenSUSE, Ubuntu 14.0.X & 15.0X, Windows 64bit (also desktop clients upon request) Combination of Ceilometer and other monitoring tools (working on an Openstack monitoring tool which interfaces to ceilometer)

10 Implementation, the nitty gritty story Base install of Admin node done via Admin appliance from SUSE Studio Networking in small steps with long design times Several attempts failed due to human error Research and performance test, failed hardware Failover tests, plug the chord tests Burning the house down!

11 Enterprise..: What Enterprise wants, wants enterprise class support Enterprise gets runs large portions on: Windows, Active Directory, Exchange, ERP Systems (SAP) wants flexibility on the vendors side wants to control the resources and be able to manage their own Virtual Datacenter increasingly would like to have proper budgeting, foreseeable costs per month wants reliability

12 Target Market: Target Market/ Target Products Customers who know what they want and are looking for environments, not just a VM Any size company that have the need to grow their infrastructure Development Companies who need test and development environments (SAP, Linux development, Microsoft products) Target Product examples: Delayed replication environments Upgrade path environments Test and development environments Production environments that need flexibility, scalability and reliability
