Public Cloud
• With Public Cloud “2 people business” can have:
– ERP
– CRM 196,802 soho ( up to 9
– Manufacturing Software
companies employees)
– VOIP
• Soon they will have applications that corporate IT
does not have! Example: Video Application

Fabric Computing
• The Goal is to create a very flexible, elastic infrastructure on which a variety of
applications can be easily provisioned and efficiently operated.
• Interconnected nodes that look like a 'weave' or a 'fabric' when viewed
collectively from a distance
• The main advantages of fabrics are that a massive concurrent processing
combined with a huge, tightly-coupled address space makes it possible to
solve huge computing problems and that they are both scalable and able to be
dynamically reconfigured
• Challenges include a non-linearly degrading performance curve, whereby
adding resources does not linearly increase performance which is a common
problem with parallel computing and maintaining security.

STKI Round Table


Performance
• It took as ages to find out that unknown
insignificant parameter caused serious
performance issues
• We had some performance issues so we
upgraded the storage. But now we found out
that the bottleneck was networking. Than it
were the servers…


Downtime
• We had one patch causing problems with one
infrastructure component. Then, after fixing this
problem, it started to harm the application…
• Root cause analysis of production errors is a
nightmare. The general Enterprise System
Management environment is not capable to lead us
to the right place of error.
• We waited 3 hours for the storage vendor support
then another 4 hours to the network person but then
the storage support personal had to leave….


Operations
• Dependencies between infrastructure components are so
complicated. Updating one system component takes ages
until getting certification from all other related components
• Professional services from the different technology domains is
huge cost
• It’s a lot of fun to go through 4 management consoles each
with a different GUI and methodology
• It took us ages to automate adding new server to the
application server cluster. Then we had to do it almost again
since the server OS changed some API’s


Time to market and efficiency
• We have to show efficiency all over the road –
reduce development, testing and release
cycles
• We are spending too much time on “none-
core” issues
• We are not efficient enough
• Integration problems between components
caused serious delay in deadlines


Server Ratios - Windows
• Number of Windows Servers (logical ) per System member
Per FTE All Win Prod Win
Servers Servers
25 percentile 92servers 47servers
Median 122 Servers 67 Servers
75 percentile 200 Servers 100 servers

• Percent of Production Windows server from all Windows servers

Percent of
prod servers
25 percentile 50%
Median 62%
75 percentile 75%

NOC, Operators Ratio
• Number of Open production servers per NOC person:

Per FTE Unix Linux Servers
25 percentile 15servers
Median 46 Servers
75 percentile 80 Servers
• Large variety since there is large variety in NOC operations
• MF, AS/400, OpenVMS – not included in the count but add lots of load

Appliances
We are seeing more and more Appliances offerings

NetBackup 5000
Appliance Oracle Exadata
Teradata EMC Greenplun
Turnkey Deduplication Solution from
Symantec
Exalogic

VBLOCK
Google FlexPod for Vmware

The role of System is changing
• The “System” is changing:
– From HW and OS centric that is focused on the
particular platform
– To integration between systems, connectors and
XML
• More “business process” oriented – need to
know what the application is doing and what
is the business process even before installing
a patch
