Success in Cloud Computing

Journey to the Cloud with Red Hat – Technical Event Series – May 20153

CLOUD DRIVERSI.T. Transformation for everyone


REAL LIFE IS “OLD SCHOOL”...Customers expectations have changed

1. You need to get to market sooner

2. You need to deliver your services anywhere, on any device and at any time

3. You need to scale your services dynamically

4. You need your infrastructure to be cost efficient

“Old School” infrastructure & methods don't cut it...


I.T. IS EVOLVINGAn evolution is taking place across the entire software development life cycle


RENOVATE TO INNOVATETo deliver business value you need flexible IaaS and PaaS platforms


CLOUD DEPLOYMENT MODELSAn Open Hybrid Cloud delivers the choice required


WHY AN “OPEN” HYBRID CLOUD?An Open cloud adds the following key characteristic

● On-demand self service● Broad network access● Resource pooling● Rapid elasticity● Measured service

+Workload Portability

JOURNEY TO OPEN HYBRID CLOUDBuild progressively on what you have today, to deliver an Open Hybrid Cloud


RED HAT'S PATH TO THE CLOUDStart with your existing workloads (both physical & virtual)… no need to “rip and replace”

RED HAT ENTERPRISE LINUXPortable workloads across hybrid clouds


WHAT ARE LINUX CONTAINERS?Software packaging concept that typically includes an application and all of its runtime dependencies

● Easy to deploy and portable across host systems

● Isolates applications on a host operating system

● In RHEL, this is done through:● Control Groups (cgroups)● Kernel namespaces● SELinux, sVirt, iptables● Docker

Packaged dependencies = faster boot times + greater portability


ESTABLISHING CONTAINER STANDARDSRed Hat works with the community to drive standards for containerisation

ISOLATION WITH LINUX CONTAINERS

● Isolating applications on host operating system

● Security

● Portability across host systems

CONTAINER FORMAT WITH DOCKER

● Interface for communications, configuration, data persistence, provisioning

● Content agnostic

● Infrastructure agnostic

ORCHESTRATION WITH KUBERNETES

● Orchestrate containers at scale

● Define application topologies

● Handle container networking

● Manage container state

● Schedule across hosts

REGISTRY CONTAINER DISCOVERY

● Trusted container images

● Federate consumption libraries

● Promote consistency and reuse

Unlock the Value of Cloud for Your Business


THE GOLD RUSH MENTALITYDon't just “lift and shift” your way to the cloud…you'll miss the real gold!


NO “ROACH MOTELS”Applications should be able to check in and check out of your cloud


CERTIFIED CLOUD PROVIDERSConsume services on demand and enable workload portability

Via Red Hat's Certified Cloud Service Providers you can:

- Consume subscriptions on-demand

- Take your existing subscriptions to the cloud

PLUS MANY MORE...


CLOUD INFRASTRUCTURE IS...

TRANSIENT

It can disappear

ANONYMOUS

You may not always get the same infrastructure back

MULTITENANT

The infrastructure is shared and you could get noisy

neighbours


Pets / Traditional Cattle / Cloud

ERP

Payroll

Accounting

CRM (unless it's Salesforce)

E-commerce

Greenfield app development

MapReduce jobs (Hadoop)

Real-time analytics

WORKLOAD REQUIREMENTSThe differences between traditional and cloud workloads


CLOUD-ENABLED APPLICATIONSYour applications should have the following characteristics

● Dynamic addressing● Distributed systems● Asynchrony● Statelessness● Elastic Databases● MapReduce – Cluster

Computing


DYNAMIC ADDRESSINGApplication components are transient, so they can't use fixed addresses

TRADITIONAL CLOUD


DISTRIBUTED SYSTEMSDe-couple and distribute application components – Micro Services

TRADITIONAL CLOUD


ASYNCHRONYDecouple in time as well through asynchronous service calls (i.e. use messaging, queues)


STATELESSNESSExternalise session state from applications to the client, or via cache

TRADITIONAL CLOUD

CLUSTERED, SYNCHRONISED APPLICATION SERVERS STATELESS APPLICATION NODES


ELASTIC DATABASESUse No SQL data stores to horizontally scale; or at least cache with data-grids

TRADITIONAL CLOUD


MAPREDUCE – CLUSTER COMPUTINGHorizontally scale and parallelise processing

TRADITIONAL CLOUD


AUTOMATE EVERYTHING!Manual and operator intervention tasks will erode value...quickly

Lower total cost of ownership

Greater I.T. efficiency

Increased productivity


START WITH AN ISLAND PROJECTDon't try to “boil the ocean”; build, learn, celebrate and iterate...


TRAIN FOR SUCCESSEnsure your team has the skills to succeed through training & experience

Red Hat has training courses & certification in:

- All products such as: RHEL, RHEL Open Stack Platform, OpenShift, Satellite...

- But (very soon!) also solution based, such as: DevOps, Containers, Cloud...
