Why applications development in the cloud?

New economics

• Pay for what you use

• Shift from capex to opex

• Accelerate time to value

Speed

• Faster deployment

• Reduced patching or maintenance

• Reliability and fault-tolerance

Agility & innovation

• Enable new apps and services

• Latest software for users

• Internet collaboration/ global reach

Applications in the cloud

Perception

“Cloud is about operations and infrastructure”

Reality

The business is concerned with user services (i.e. dev & ops together)

Cloud ROI depends on application DNA

“All applications make sense in the cloud”

Only apps with certain usage profiles are an economic fit for the cloud

“Apps can just be moved to the cloud for cloud benefits”

Cloud has implications for HOW applications should be built


DevOps

IT Operations

Keys to bridge the gap:

“Build to run” “Regular releases reduce risk”

Quality

Automation

Collaboration

Agile Delivery

Apps / Dev

Continuous Delivery


“Developers, especially for home-grown applications, may do many nonstandard things (make calls to the hardware, make assumptions about the network infrastructure or environment it is running in, and so on).

You have to think differently if you are building applications that will run across wide-area networks or across data centers.”

– CIO, software vendor

The key application considerations

Application ‘cloud-readiness’

Performance

Application elasticity drives cloud economics. Apps must be designed to scale up for agility AND down for cost savings.

An under-performing application can negate the savings promised by the cloud.

In the cloud, it is more important to anticipate and proactively handle failures.

Cloud brings new risks for apps in a shared environment. Security should be built-in, verified and monitored.

Resilience

“Early customers of [leading cloud provider] found this out the hard way when the service had a short outage. When it returned, many customer’s applications didn’t.” - Forrester

Source: Forrester Research, Inc., Best Practices: Infrastructure as a Service, September 2009

Resilience: elevated in importance

Less control and visibility of the environment• Network & disk performance variance due to multi-tenancy of cloud

Must design, implement, & test for auto-recovery from failure• Assume hardware will fail; assume outages will occur; assume your application will fail


Resilience: Our approachResilience

Operation Model

Infrastructure: SLO dependent• Choose the correct Cloud infrastructure configuration

Application: Define behavior as operations• Create

• Shutdown

• Restart / restore


Security: key cloud problems

Lowest common denominator

Cloud is a sharedenvironment

Attackers seek access though weaker, adjacent apps

Limited control & knowledge of public cloud infrastructure

Hypervisors, guest and host OSs have vulnerabilities

Data needs to be encrypted for security & compliance

Cloud apps often rely on 3rd party components

You don’t have assurance they are secure unless you test

Web services are rarely effectively security tested

Low control of environment

3rd party components

Security


Security: Our approachSecurity

“Architecting security in” from the beginning

Early and continuous• Address all phases of the application lifecycle

• Automate application security testing

Different tools available for specific customer requirements• HP Fortify

– Static testing, mobile testing, penetration testing, ..

• HP WebInspect


Applications delivered in a virtual private cloud

Success Story

Improve business agility and responsiveness with faster time to market & cost-effective services:

• Highly efficient scheduling application for pilot training on the flight simulator

• Secure repository for crew manuals and documents; airplane issues and maintenance log for audit & compliance; access to electronic flight checklists, charts, maps, etc.

• Secure environment to host a Safety & Risk Management application

Business need

Pre-built, off-site cloud service with servers, storage and network:

• Design and host cloud flight simulator scheduling tool and develop portal interface

• Host : storage for manuals with Enterprise-class security.

• Design and host AQD SMS application to collect an administer safety incidents.

HP solution
