What is the Cloud?

“Simply put, Cloud Computing is the delivery of computing services, including Servers, Storage, Databases, Networking, Software, Analytics and Intelligence – over the Internet (“The Cloud”) to offer faster innovation, flexible resources and economies of scale.”

Common Examples of Cloud Services:

Infrastructure As A Service (IaaS): Platform As A Service (PaaS): Software As A Service (SaaS):

Comparing On Premise vs Cloud options

You Manage Others Manage

In Infras astr truc uctur ture e as as a a Ser ervic vice e (IaaS IaaS)

• Cloud infrastructure services – highly scalable and

automated computer resources (servers, network,

• perating systems and storage in a virtual

environment)

• Provides remote, outsourced data centre services.
• Easy to automate deployment of storage,

networking, servers, and processing power

• Hardware resources can be based on consumption

and purchased as-needed

• Highly scalable

Pla Platf tform as as a a Ser ervic vice e (PaaS aaS)

• Builds and manages infrastructure that provides a

development and deployment environment

• Customers purchase the resources they need to

develop or customise cloud-based applications.

• Provides a secure environment and tools that reduce

the amount of coding needed to create anything from simple cloud-based apps to very large enterprise systems.

Sof Software a as a a Se Service ce ( (Sa SaaS) S)

• Use software applications over the internet, on demand

and typically on a subscription basis. (e.g. Microsoft Office 365)

• Accessible over the Internet from any device with web

access

• Users are not responsible for the hardware or software

updates and maintenance.

Ad Advantages:

Cost Reduced up-front cost for infrastructure. Scalability Elasticity and capacity provides more or less computing resources depending on need

Performance and Security Cloud computing services run networks of secure data centres which should be regularly upgraded and professionally maintained. Productivity and Speed Provided as a self- service and on- demand so time- consuming onsite IT management and admin is reduced Reliability Data backup, disaster recovery and business continuity are improved when set up correctly and managed professionally

Dis Disad advan antag ages:

Downtime Service outages and reduced performance are inevitable and unavoidable in locations with poor internet reliability Lack of Control Users must have a high level of trust in their provider Cost High pay-as-you-go fees may work out more expensive Potential Vendor “lock-in” What happens if you want to change cloud service provider? Vulnerability to Attack Data centres are a potential target and must be vigilant and professionally managed.

Le Legislative Con Consideration

• ns

The Privacy Act 1988 (Privacy Act) and the Australian Privacy Principles (APPs) promote and protect the privacy of individuals by regulating how

• rganisations handle personal information.

Health and Medical Research Activities utilize the most sensitive types of personal information and therefore additional protections are required. Notifiable Data Breach (NDB) amendments introduced in 2017 obligates entities to report eligible data breaches. (NB failure to comply exposes entities to penalties, including fines up to $1.8M).

Tips to think about:

• 1. Understand how using the cloud fits into your overall business

strategy

• 2. Complete a full audit of hardware and software at site to identify

what may be suitable to migrate to the cloud

• 3. Consider what services may need to upgrade to be cloud-ready
• 4. Check internet speed and assess reliability
• 5. When reviewing potential cloud service providers, check:
• SLAs
• Privacy Policy and Safeguards
• Location where Data is stored

6. Understand that the same privacy and security risks still apply in the cloud so this will still require governance. 7. When budgeting, factor in usage and growth changes that may increase today’s running costs. 8. Carefully monitor your cloud usage so as not to get bill shock 9. Make sure you have a robust business continuity plan that allows you to operate in some capacity if you cannot access your cloud systems.

Con Conclusion

• n:

Cloud technology is not a perfect solution to manage patient care and data in every healthcare environment in today’s market. But it does offer significant opportunities in the right situation. Hurdles exist but with proper education, the right framework and good governance, healthcare providers can take advantage of this rapidly growing and useful technology.
