Chapter 5. Services > Exercises
Exercises
| 1. | List all the services that you can think of in your environment. What hardware and software make up each one? List their dependencies. |
| 2. | Select a service that you are designing or can predict needing to design in the future. What will you need to do to make it meet the recommendations in this chapter? How will you roll out the service to customers? |
| 3. | What services rely on machines that do not live in the machine room? How can you remove those dependencies? |
| 4. | What services do you monitor? How would you expand your monitoring to be more service based rather than simply machine based? Does your monitoring system open trouble tickets or page people as appropriate? If not, how difficult would it be to add that functionality? |
| 5. | Do you have a machine that has multiple services running on it? If so, how would you go about splitting it up so that each service runs on dedicated machines? What would the impact on your customers be during that process? Would this help or hurt service? |
| 6. | How do you do capacity planning? Is it satisfactory, or can you think of ways to improve it? |
| 7. | What services do you have that have full redundancy? How is that redundancy provided? Are there other services that you should add redundancy to? |
| 8. | Reread the discussion of bandwidth versus latency (Section 5.1.2). What would the mathematical formula look like for the two proposed solutions: batched requests and windowed requests? |
