What is Cloud Computing? • Internet-based computing composed of large groups
of remote servers networked together to allow for shared data storage, processing tasks, and access to resources.
• Can be private, public, or a combination.

Evolution Mainstream Grid Computing
– Collection of computing resources to complete a common goal
1990’s Utility Computing – Provisioned model of pay-for-service; the end of the flat rate
Early 2000’s Software as a Service – “on-demand”; subscription basis pay-for-service
Modern-day Cloud Computing – Next generation “data centers”; combination of the above three

Perceptions & Misconceptions • Enterprises are still experimenting with cloud.
– FALSE - Enterprises are actually investing more than 10% of their annual IT budgets on cloud services
• Security concerns restrict options for using the cloud. – FALSE Public cloud providers are making considerable
investments to strengthen security architecture • Cloud is relevant only for technology needs.
– FALSE - 56% of enterprises consider cloud to be a strategic business differentiator that enables operational excellence and accelerated innovation
• Cloud consumption is simple. – FALSE - 65% of enterprises believe they need help to deploy
cloud solutions as most lack the internal IT skills and expertise needed

Cloud Challenges
Privacy/ Security
Ease of Use/ Costs
Migration
![Page 56: Racing to the Clouds: How Cloud Computing is Advancing ... › conferences › proceedings › ...– FALSE Public cloud providers are making considerable investments to strengthen](https://reader033.vdocuments.us/reader033/viewer/2022060405/5f0f0d887e708231d4424149/html5/thumbnails/56.jpg)
Privacy & Security Challenges
• Privacy & Security is and always will be top of mind. – However, the greater direct control cloud users have
over hardware and software, the more control over management of privacy is attained
– Establishing an effective and appropriate legal structure for regulating cloud computing services is imperative.
– Internal and regulatory/legislative policy issues – Privacy issues arise from how data is managed and
not where it’s located
![Page 57: Racing to the Clouds: How Cloud Computing is Advancing ... › conferences › proceedings › ...– FALSE Public cloud providers are making considerable investments to strengthen](https://reader033.vdocuments.us/reader033/viewer/2022060405/5f0f0d887e708231d4424149/html5/thumbnails/57.jpg)
Ease of Use Challenges • “Click to buy”’ additional services
– It is very easy to set up new servers and purchase additional services that increase costs. This benefit also creates a significant challenge
– Internal process & controls – Admin rights – Monitor and manage utilization – Provider tools available
![Page 58: Racing to the Clouds: How Cloud Computing is Advancing ... › conferences › proceedings › ...– FALSE Public cloud providers are making considerable investments to strengthen](https://reader033.vdocuments.us/reader033/viewer/2022060405/5f0f0d887e708231d4424149/html5/thumbnails/58.jpg)
Migration Challenges • Migration from legacy system(s) to cloud
hosting is a major effort. – However, this effort can substantially reduce IT-
related expenses by eliminating costs associated with repairs, software upgrades and license renewals as well as keeping up with latest privacy and security technologies and practices
– Training, education and certification

Challenges and Solutions • Major Challenges:
– Business/IT: • Legacy entrenchment vs Agility • Fear of the unknown • Lack of credibility
– IT/Business • Security / Governance • Supportability • Accountability • Reliability
• What are the Missions of our Customers? – Lack of Communication between areas
• Customers Issues – esp., with Public Health Data – Usage of Shared Environments – Hosting in another state – What laws have jurisdiction? – Latency Issues – ex., lab instruments
• Solutions – Build Proof-of-Concept models – Develop Agency Wide Policies – SPARC

On Premise vs Cloud KPI On Premise Cloud
Vertical Scaling Ability to dynamically add more resources to an existing application or more applications to a deployed instance. Would allow us to easily INCLUDE additional in-scope apps – without re-architecting a hardware HLA.
X
Dynamic Expansion Automated expansion of CPU, Memory and Storage – without user intervention. Dynamic Monitoring Tools that provide insight into current usage.
X
High Operational Cost The operational and over head cost can be lowered considerably because of the self-service infrastructure and other cloud based services. Redundant IT recourses like system admins/DBAs can be reduced. Apps can be developed better, faster and in scalable way which can reduce maintenance cost.
X
High Availability Load balancing possible – without any additional infrastructure manual maintenance. Load balancing across GEOGRAPHICAL boundaries also possible (and easy). Cost savings in Load balancing software, additional firewalls etc.
X
Disaster Recovery Master – Master Replicated Servers , with ‘hot-swapping’ (automatic failover) in case of Disaster. Replication across ZONES (geographical boundaries) possible.
X
Turnaround time Short turnaround for provisioning new servers, for modifying existing servers. Often, a simple web based point and click to provision new instances.
X
License optimization A best effort utilization of X licenses for Y cores – that would span across multiple Applications – providing cost savings. X

Hard Decisions & Realizations
• Realize the Cloud Architecture isn’t the “End-All” solution
• Hybrid Architecture – Using some Private/Public Cloud and some on premise – We do have “on premise clouds”; ex., using 3rd party
vendors to provide services - DCS • Take baby-steps • Communication!!
– Understand the business requirements / mission statements
