AWS EC2 InstancesJune 7, 2019 AWS
Amazon EC2 is here to offer the choice of many sample types that can be optimized to suit different use cases. All kinds of examples have achieved such a combination, such as CPU, storage, memory, and network capacity. This also gives you flexibility in choosing the right combination of features for each application. For each example class, it includes one or more sample sizes to allow scaling of resources according to the requirement to achieve the target workload.
For each of the examples, Amazon EC2 provides a consistent and predictable amount of CPU capacity and no hardware conditions. It also provides the necessary resources for the personal computer for each sample, respectively.
Amazon EC2 instance types
The Amazon EC2 instance will provide a variety of options in the example type, which one special optimized to suit different use cases. In general, the type of institution will contain various combinations of memory, network capacity, CPU, storage gives flexibility in order to choose the perfect combination of features for your applications. The type of each instance of Amazon EC2 typically contains one or more examples of the workload size and hence the power destination.
EC2 instance types are generally classified into 5 types by Amazon. They are:
- General Purpose
- computer optimized
- Memory . optimized
- Accelerated computing
- Storage Optimized
Type: General Purpose
The overall goal of the agency is the most widely used and is a good first step if you have a new or for AWS cloud computing in general. They offer a great combination of cost and functionality, with the use of them oriented to a web server, execution environment for the development of games or applications for mobile devices and to run business applications such as CRMs and ERPs. You will find that one of the main differences between the classes of institutions and fixed vs. Burstable Performance. C2S with a Burstable performance, which will have the ability to quickly scale this computing power — the price of one.
The overall goal: A1
A1 branches is the use of common, but differentiate by being an offer based on ARM, while Intel or AMD. For example, this platform will be of interest to the community and to develop ARM applications that run open source software such as Java and Python, and some tend to support this architecture.
The overall goal: M5
M5 agencies that run on Intel Xeon processors and are therefore suitable for the development of the x86 architecture. They offer high processor, memory and network performance when compared to the A1.
The M5 agencies are great for developing and testing the Web server environment as well. It also provides support for the Intel AVX-512, a set of instructions that benefits from CPU processing of encryption algorithms, so the agency is a great choice when critical security does not affect performance.
The general objective: T3 and T3a
T3 and T3a is that offers Intel and AMD’s Burstable performance institution. Burstable agencies perform great if you want to give up cheaper and slightly less powerful than the example of performance debris (like an M5), but still want the option to be able to scale quickly to calculate workloads to manage, so “bursts” of power.
These bursts of energy do not come for free — they are regulated by CPU credits. In general, if you do not perform the maximum processing power, you will earn CPU credits. The number you earn depends on the time at a low limit and the size of your example. If it has been broken, the credits have been spent.
Type: Computing optimized
Calculate optimized C5
C5 agencies are ideal for applications in which computer raw energy priorities such as game servers, scientific modeling, high-performance web server, and media transcoding. The C5 agencies work with Intel Xeon Platinum processors and as a benchmark 25 percent faster than previous C4 generation institutions — a clear example of the benefits of improving the generational energy cloud.
Type: Memory optimized
Memory optimized: R5 and R5a
R5 and R5a is that Intel and AMD offer optimized “common” memory cases. This agency is ideal for memory-intensive applications such as real-time analysis of large volumes of data, large memory caches, and a high-performance database. Agencies R5 and R5a benefit from the Nitro AWS System, which gives access to almost all computer and memory resources on a server (that is, assigning as little as possible).
Memory optimized: X1 and X1E
agencies X1 and X1E are optimized to provide a high proportion of memory for computing and the X1E family providing the highest memory to calculate the relationship between EC2 offer. This institution used to be the highest memory-intensive applications, such as SAP Hana, provide a solid foundation for real-time applications.
Memory optimized: high memory institutions
Memory institutions have a large amount of RAM available for the largest, providing 6 TB 9 TB or 12 TB of memory in a single sample. Like the X1 / X1E, it was suitable for production deployments that consume lots of huge memory in real time, such as SAP Hana.
An important caveat with high memory agencies is that they are only available on dedicated 3 year collecting hosts. This means that you will have to commit to purchasing 3 years but you will get the security benefit to the host on which it is dedicated, it is you will have your own server for themselves and will not share as AWS will not sacrifice the other.
Type: computer acceleration
Accelerated Computing: P3, G3, F1
Accelerated Computing Agencies make a separate graphics unit (GPU) or field programmable (FPGAs Gate Arrays) optimized for specific tasks such as video processing calculations or floating point numbers. Sacrifice is an example:
- P3: These are the general GPU offers, good for learning machines and apply stable parallel processing skills.
- G3: These are special GPU offerings for intense graphics tasks such as rendering, encoding and streaming.
- F1: These are agencies that offer FPGAs for accelerated process. You can leverage FPGAs several ways over time to repair differently, and all this has been aided by the specific custom of the Amis FPGA (called AFIS), which offers faster implementation and development options compared to conventional FPGAs.
Type: Storage Optimized
Storage Optimized: H1 & D2
H1 and D2 agencies are part of the offering, which provides a high data warehouse with solid read and write sequencing for a set of large deployments such as Hadoop. H1 and D2 agencies provide a huge warehouse on the HDD, the H1 provides a maximum of 16TB and D2 provide a maximum of 48TB.
Storage Optimized: I3
Agency i3 offers warehouse at most SSD just under 16 GiB. However, these institutions provide lower latency HDD storage and also offer AWS Nitro system is optimized to access memory and computer power (also called “Bare Metal” access).
