4. What is Cloud Computing?
Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet
a collection/group of integrated and networked hardware, software and Internet infrastructure (called a platform).
Using the Internet for communication and transport provides hardware, software and networking services to clients

Cloud Computing
The platform provides on demand services, that are always on, anywhere, anytime and any place.
Pay for use and as needed, elastic
scale up and down in capacity and functionalities

7. Why Cloud Computing for SDWIS State?
Last delivery of SDWIS State product suite in 2012 – Java 6/7
Current SDWIS State not compiled for Java 8 or later (user support bulletin January 21, 2016)
preliminary testing indicates key functions of SDWIS/FedRep, SDWIS/STATE and other SDWIS applications work with Java 8 but there are known issues with at least the reporting functions of these applications (i.e. the SDWIS/STATE Compliance Determination reports and SDWIS/FedRep reports and job listing/details functions) with update to Java 8
Increased risk each year to update SDWIS State to latest version of Java
U.S. Environmental Protection Agency

8. Why Cloud Computing for SDWIS State? Cont’d
States servers are vulnerable using a JVM version 7 as opposed to latest version
SDWIS State on Cloud server isolates the java vulnerability off the State’s network/infrastructure.
Keeps data secure (data centers provide security)
Keep running SDWIS State until move to SDWIS Prime
Allow state to continue use of their interfacing applications until move to SDWIS Prime
Gives state time to make transition to SDWIS Prime

9. Georgia SDWIS State on Amazon Cloud
Moved SDWIS State to cloud in 2010
Lower IT infrastructure cost primary driver
Running SDWIS State 3.33 Product Suite on Amazon Web Services
Oracle Database as service
Java 7/Tomcat 6 with Apache and Nginx
GA’s Non-SDWIS apps deployed from GA IBM Cloud Servers connect to/extract data from SDWIS/STATE DB on Amazon Cloud
U.S. Environmental Protection Agency

10. Georgia SDWIS State Cloud Environment
Georgia has control/ownership over its SDWIS environment
GA has three cloud servers (database server, application server and small Linux server)
Oracle as Services provide
Oracle patches/updates
Nightly DB backup
Backup saved for default of 7 days but # days saved is configurable (e.g. 15, 30, 60 days)
Servers support both test and production environments for SDWIS State and SDWIS product suite (FedRep, SDWIS Bridge, XML sampling etc.)
Cloud Linux server is used for the public facing application for Drinking Water Watch

13. Georgia SDWIS State Cloud Security
VPN connection is set up for GA state user access to the system
Amazon Cloud provides security based on their certification level (FISMA compliant)
Java Security risk mitigated by
Amazon data center physical security
VPN user access
Firewall rules
Use of proxy web servers

Cloud Costs
GA medium size state and data storage costs are based on data size
Costs for Amazon are being paid by GA directly
Licensing for Oracle Database Service included in Amazon cost
Amazon costs approximately $600 per month for GA set up

Cloud Support
SAIC continuing to provide Administrative support (have had minor issues so far)
SAIC handling operations and maintenance for GA but could be done by state
SAIC provides additional support for trouble shooting

16. Migrating to Cloud Benefits
States have control over their SDWIS environment once setup
Same database server could host multiple smaller schemas – e.g. States with smaller databases could share a DB server
Single app server can host multiple instances of an application (e.g. GA’s Amazon app server hosts its Production and Test instances of SDWIS applications)
Eliminates stand alone server need in state
Costs for state infrastructure moved to Cloud costs and contract support costs
More and possibly quicker access to contractor support than state IT support in some cases
U.S. Environmental Protection Agency

17. U.S. Environmental Protection Agency
Migrating to Cloud
Cost Considerations
Costs are based on usage as well storage needs and number of servers needed or different set ups
Each state needs will be dependent on size and system needs (add on applications and format for the system)
Database Licensing for Oracle or SQL Server on Amazon Cloud can be through Amazon or bring own license
