New product experience: Alibaba cloud's new generation of local SSD instance I4 open beta

In recent days, , Alibaba cloud elastic computing announces a new generation of local SSD example i Series specification family open beta .i4 The instance specification family is based on Alibaba cloud's third-generation DPCA architecture , Single disk storage IOPS the height is 60 ten thousand ; With Intel Ice Lake CPU processor , Compared with the previous generation of local SSD example i3/i3g, single vCPU Calculate the force promote 23%, Calculation force of the whole machine promote 52%; Configuration is high IOPS、 Big throughput 、 Low access latency local NVMe SSD,IO Delay Reduce 10%; Single disk capacity promote 100%, the height is 1920 GB.

new generation i Series local SSD example i4 It is divided into i4g and i4r Two specifications , The former CPU The memory ratio is 1:4; The latter is 1:8, It is a new specification of this generation , It can meet the needs of larger memory scenarios .

On the pan Internet 、 Intelligent terminal 、 logistics 、 Travel 、 In industries such as finance , database 、 Big data storage intensive applications are common in enterprise core systems . Such scenarios are more dependent IOPS、 Throughput performance 、 Lower read and write latency , And the application has a multi copy mechanism to ensure data reliability . Enterprises want to have the choice of low-cost storage and high-performance storage . Alicloud local SSD example i4g/i4r Will be the best choice for enterprises .

i4g/i4r Local SSD Examples apply to OLTP and OLAP、 High performance relational database ,NoSQL database （ Such as Cassandra、MongoDB etc. ）,E-MapReduce Big data hot and cold data layering 、 Storage computing separation 、 Data lake, etc , as well as Elasticsearch And so on . big data TPC The assessment shows , comparison i3g,i4g Instance product TPCx-HS performance promote 61.8%,TPC-DS promote 28.21%.

Local SSD The instance has the advantages of low storage delay , But there are no three copies in the local storage , It is required to have the ability to quickly handle faults on the operation and maintenance side . In view of this , Alibaba cloud has passed AI The algorithm predicts in advance what will happen CPU、 Memory 、 Disk and other hardware failure , And push the alarm to the user , Users can build an automated operation and maintenance system by subscribing to such active operation and maintenance events , Ensure high application stability , Reduce the risk of business interruption .

meanwhile , Alibaba cloud also provides on demand services / Preemptive example 、 Flexible supply and other payment modes , Flexible combination , With elastic scalability, the expansion and contraction capacity of resources can be realized , Take advantage of the elasticity of the public cloud to help users better realize cost optimization , Enhance the competitiveness in the era of big data .
