00:00Welcome to this module on OCI Compute. Let's start with an introduction.

00:10So, OCI Compute service provides you virtual machines and bare metal servers to meet your

00:16compute and application requirements. The three defining characteristics of this service

00:21include this scalability, high performance, and lower pricing. In the next few slides,

00:27I will talk about each of these in a bit more detail. So, the first thing in the OCI Compute

00:34service is you have this notion of flexible shape. What does it mean? Well, it means you could choose

00:40your own cores, your CPU processors, and you could also choose your own memory. And as you can see

00:46the sliders here, you could choose a combination of CPU cores and memory, and there's a ratio there,

00:52but you have flexibility in choosing your own configuration. Literally, there are thousands

00:57and thousands of configurations you can choose from. Now, what is the use of doing this? The use

01:02of doing this is you could select the right machine type by using our flexible shapes. And in the cloud,

01:09there's this notion of t-shirt sizing. So, you have a small, medium, large kind of shapes,

01:15and your application has to fit those shapes. And either sometimes you over-provision or under-provision

01:22and you have to go through that painful process of changing your machine types. We hope with these

01:27flexible shapes, you don't have to do that. If you still want to use the traditional approach,

01:33we have virtual machines, we have bare metal servers, and we have dedicated host. And you could

01:38use either one of them or all of them. In bare metal servers, basically means you get a full machine,

01:45a full server, which is completely dedicated to you. Dedicated host basically means that you get a full

01:52dedicated bare metal machine. But on top of that, you could run virtual machines. What's the difference

01:57between dedicated host and VMs? Well, VMs, as you see in the slide here, are shared and multi-tenant,

02:04meaning the host can be running VMs from multiple customers. They have strong security isolation.

02:10So, you don't have to worry about that. But some customers want a dedicated host where they could

02:15run their own VMs and the VMs, they don't have VMs from any other customer running there. So,

02:21that option is also provided by using dedicated host. Not only this, but OCI is only one of the two

02:29cloud providers to provide you options on processors. So, you can run AMD-based instances,

02:35you could run Intel-based instances, and you could also run ARM-based instances are really a powerful

02:42thing for mobile computing. The phones you are using today are probably running on ARM processors.

02:48Now, ARM is coming into the data centers. So, today, we are using Ampere Ultra processor family,

02:56Ampere A1 instances are performed very well in many use cases. So, as you can see on the screen here,

03:03we are using Nginx, some price performance number. It's a good example of high-throughput workloads

03:08like web servers, microservices, API gateways. In ARM's testing of Nginx as a reverse proxy request

03:16per second, you can see here that Ampere A1, which is the processor we are using for ARM,

03:22had 32% better price performance than the equivalent AMD processor and 69% better performance

03:29than Intel processors. So, this really talks about our industry defining price performance

03:36capability, particularly with ARM processors. And finally, on the pricing side, the service

03:42implements pay-as-you-go pricing. We are 50% cheaper than any other cloud out there just to begin with.

03:49And not only that, you could use something like a preemptible VMs to reduce your cost by more than

03:5550% from your regular instances. Preemptible VMs are low-cost, short-lived VMs suited for bad jobs

04:02and fault-tolerant workloads. These are similar to regular instances, but price 50% lower. So,

04:09you can use them to reduce your cost further. So, just to recap, very powerful service. The three

04:16defining characteristics we talked about, this notion of scale, this notion of higher performance,

04:22we saw an example of that and lower pricing provided by the compute service. I hope you found

04:28this lesson useful.

04:31Thanks for watching.
