Smiths Security Ltd is a company that runs numerous Security businesses throughout Australia. Its head office is located within Sydney Metro. These businesses include Armoured Vehicles, Security Guards, Fire Monitoring Services, Alarm Monitoring and a number of related businesses.
It currently has a data centre in each of the major cities (Sydney, Melbourne, Brisbane, Adelaide, and Perth). The major data centre is in its head office in Sydney. The company has the following server infrastructure at each site:
- 1 x Active Directory domain controller on Windows Server 2003
- 1 x SQL Server 2003 database server on Windows Server 2003
- 1 x Lotus Notes email Server
- 1 x Windows Server 2003 Print Server
- 1 x Windows Server 2003 running IIS Web Servers which connect to the SQL backend.
- 2 x Business Application Servers running custom softwareto manage their staff
This infrastructure has obviously not been updated for some time and Smiths Security IT Management Team is very concerned that an upgrading OS and Server Hardware is not worth it. The IT team is now considering moving some, or all, of their current infrastructure into a Cloud and updating some of their software (but not their business application servers).
Smiths Security has engaged you (Cloud Jump Consulting Pty Ltd) to advise on moving to the cloud and what would best suit their requirements for a highly secure environment.
1.Smiths Security has advised that they don’t want to move their business application servers to the cloud. Create a report that
a) Discuss why Smith Security is taking this view AND why you would recommend moving these to the cloud;
b)Outline the major benefits and issues for 2 approaches of moving this to the cloud (note the servers are running custom software);
c) Provide a summary of your advice to this company along with your recommendation about which option to choose. Your report should be no longer than 2 pages. (20 marks)
2.Smiths Security has the following web servers at its main site:
1 x SQL Server 2003 database server on Windows Server 2003
1 x Windows Server 2003 running IIS Web Servers which connects to the SQL backend.
a) For Smith Security to move their web environment to the cloud, what would be the best solution (IaaS, or PaaS) for each of the applications (SQL and IIS) IaaS, or PaaS? Detail your recommendation to Smiths Security; How would this change if other servers also access the SQL Server?
b) What are the differences, benefits and issues, between the two platforms (IaaS and PaaS) that Smith Security would need to consider.
3.Smiths Security no longer wants to use Lotus Notes and plan to migrate this and other business applications (Spreadsheet, Word processing) to the cloud. They are not sure what model to choose and what applications so are looking to Cloud Jump Consulting Pty Ltd to provide some recommendations. They also want to enable collaboration between staff at the various sites.
a) What are the major differences between the models IaaS, PaaS and SaaS?
b) Discuss 2 models (from IaaS, PaaS, and SaaS) that you consider most appropriate for these services and discuss why these models are the most appropriate for their mail, spreadsheet, and word processing.
c) Recommend one of the two models you discussed and advise what the most likely problems that Smiths Security will encounter with this model. How would you advise Smiths Security to deal with these issues?
