With shared hosting and overcommitment, larger virtual machine (VM) density can cause noisy neighbor problems, where a small number of applications can monopolize all resources such as network bandwidth, CPU, RAM and disk input/output (I/O). Disk capacity increases but the speed of reading and writing does not. This causes performance to be spread over more […]
In my previous posts (Part 1, Part 2), I compared the sensor and auto cook functionality of microwave with auto scaling in cloud and discussed the agility and adaptability provided by a cloud. In this part of the series, I compare additional aspects: reliability, multiple devices, compliance and acceptable use. Reliability A microwave oven can […]
Put a bar of a brand of soap that floats in water on top of some wax paper and microwave it for a minute and a half. Sit back and enjoy as the bar expands into a wondrous confection of cloud formations. The bar of soap has little pockets of air inside that get hot, […]
Consider heating a glass of milk in a microwave oven. Some like it warm and some like it hot. You put in a time and start the cooking. When it is done, a ding alerts you. You can add some instant coffee or chocolate and enjoy your drink. Possibly, you may like it cold (maybe […]
Cloud computing provides the elasticity to scale infrastructure on demand. Applications with a dynamic workload demand get application programming interface (API) driven access to a flexible infrastructure to meet performance guarantees and minimize resource costs.
Cloud computing provides the elasticity to scale infrastructure on demand. Applications with a dynamic workload demand get application programming interface (API) driven access to a flexible infrastructure to meet performance guarantees and minimize resource costs. The viral nature of social media has made responding to a sudden surge in demand extremely important to prevent lost […]
I am holding back tears as I write this. Losing a guinea pig hurts a lot more than I imagined it would. Four years ago, my wife was coerced into getting a guinea pig for each of my two kids. Anyone who has had a beloved pet of any species die for any reason knows […]
When we think of cloud, two words quickly come to mind with respect to resources: virtualized and shared. We also immediately think of a scale out model—horizontal scaling. If you want to handle more load, add more machines. What about scale up? With SoftLayer, that is not an obstacle anymore. There is a choice of […]
