4 1 What is CSS? 1 What is CSS? (CSS) is a fully manage, istribute search service. It is fully compatible with open-source Elasticsearch an provies users with structure an unstructure ata search, statistics, an report capabilities. CSS works in the similar way as a atabase. CSS can be automatically eploye, where you can quickly create clusters. It provies the search engine optimization practices with zero O&M. Aitionally, it has a robust monitoring system to present you key metrics, incluing clusters an query performance so that you can focus on business logics. For etails about Elasticsearch, see the Elasticsearch Reference. Avantages CSS provies the search service on the public clou an has the following avantages: Efficient an ease of use You can get insights from terabyte-scale ata in millisecons. In aition, you can use the visualize platform for ata isplay an analysis. Flexible an scalable You can request resources as neee an perform capacity expansion online with zero service interruption. Custom wor ictionary Custom wor ictionaries are supporte. You can moify the wor ictionary without the nee of restarting the instance. Easy O&M CSS is a fully-manage, out-of-the-box service. You can start using it with several clicks, instea of managing clusters. Soli reliability You can choose to trigger snapshots manually or on a perioic basis for backup an restore snapshots to the current or other clusters. Snapshots of a cluster can be restore to another cluster to implement cluster ata migration. Functions CSS provies the following functions: Issue 01 ( ) Copyright Huawei Technologies Co., Lt. 1

5 1 What is CSS? Professional cluster management platform The CSS management console provies various function menus, allowing you to securely manage an maintain clusters at ease by using a web browser. Robust monitoring system The CSS management console allows you to view the running status of create clusters via the ashboar an cluster list. You can learn about the current running status of clusters through metric views. Support for Elasticsearch Elasticsearch is a popular enterprise-class Lucene-powere search server an provies the istribute multi-user capabilities. CSS aopts Elasticsearch an elivers multiple functions, incluing full-text search, structure search, analytics, aggregation, an highlighting. With CSS, you can achieve stable, reliable, an real- search. Issue 01 ( ) Copyright Huawei Technologies Co., Lt. 2

6 2 Application Scenarios 2 Application Scenarios CSS applies to iversifie scenarios, such as log analysis an site search. Log Analysis In this scenario, you can perform O&M analysis an fault location for IT evices as well as operation analytics base on service metrics. Statistical analysis: Over 20 statistical analysis methos an nearly ten analytical imensions are available. Real- an efficient: You can get insights within secons once new ata is store in inices. Visualize ata: CSS provies multiple report isplay moes, such as table, line chart, heat map, an clou map. Site Search In this scenario, you can search website content by keywor as well as search for commoities on e-commerce sites with recommenations obtaine. Real- search: You can get the content or commoities you want within secons or minutes. Categorize statistics: You can get categorize statistics on the searc commoities that meet conitions. Custom highlight style: You can customize the highlight style as you like. Issue 01 ( ) Copyright Huawei Technologies Co., Lt. 3

7 3 Basic Concepts 3 Basic Concepts Cluster CSS provies functions on a per cluster basis. A cluster represents an inepenent search service that consists of multiple noes. Inex Inex, similar to "Database" in the relational atabase (RDB), stores Elasticsearch ata. It refers to a logical space that consists of one or more shars. Table 3-1 Mapping between Elasticsearch an RDB Elasticsearch Inex Document Type Document Fiel Mapping RDB Database Table Row Column Schema Shar An inex can potentially store a large amount of ata that can excee the harware limits of a single noe. To solve this problem, Elasticsearch provies the ability to subivie your inex into multiple pieces calle shars. When you create an inex, you can simply efine the number of shars that you want. Each shar is in itself a fully-functional an inepenent "inex" that can be hoste on any noe in the cluster. You nee to specify the number of shars before creating an inex an cannot change the number after the inex is successfully create. Replica A replica is a copy of the actual storage inex in a shar. It can be unerstoo as a backup of the shar. Replicas help prevent single point of failures (SPOFs). You can increase or ecrease the number of replicas base on your service requirements. Issue 01 ( ) Copyright Huawei Technologies Co., Lt. 4

8 3 Basic Concepts Document Document Type Mapping Fiel An entity for Elasticsearch storage. Equivalent to the row in the RDB, the ocument is the basic unit that can be inexe. Similar to the table in the RDB, the ocument type is use to istinguish between ifferent ata. One inex can contain multiple ocument types. A ocument actually must be inexe to a ocument type insie an inex. A mapping is use to restrict the type of a fiel an can be automatically create base on ata. It is similar to the schema in the atabase. Minimum unit of a ocument. The fiel is similar to the column in the atabase. Issue 01 ( ) Copyright Huawei Technologies Co., Lt. 5

9 4 What Is Kibana? 4 What Is Kibana? Kibana is an open-source ata analytics an visualization platform an works with Elasticsearch. You can use Kibana to search, view, an interact with ata store in Elasticsearch inices as well as to visualize your ata in a variety of charts, tables, an maps. To learn more about Kibana, go to the Kibana official website: guie/en/kibana/current/inex.html Access to Kibana with a Few Clicks Kibana Functions CSS is integrate with Kibana. You can access Kibana with a few clicks, without having to install Kibana. Log in to the CSS management console. In the left navigation pane, click Cluster Management. On the isplaye Cluster Management page, locate the row where the target cluster resies an click Kibana in the Operation column. Kibana elivers the functions of visualization an Elasticsearch statistics an analysis. Specifically, it supports: Over 10 ata presentation moes Nearly 20 ata statistics methos Classification in terms of various imensions, such as an tag Issue 01 ( ) Copyright Huawei Technologies Co., Lt. 6

10 5 Relate Services 5 Relate Services This section escribes the relationship between CSS an other services. Virtual Private Clou (VPC) CSS clusters are create in the subnets of a VPC. VPCs provie a secure, isolate, an logical network environment for your clusters. Elastic Clou Server (ECS) In a CSS cluster, each noe represents an ECS. When you create a cluster, ECSs are automatically create to serve as noes. Elastic Volume Service (EVS) CSS uses EVS to store inex ata. When you create a cluster, EVSs are automatically for cluster ata storage. Object Storage Service (OBS) Snapshots of CSS clusters are store in OBS buckets. Ientity an Access Management (IAM) IAM authenticates access to CSS. Clou Eye CSS uses Clou Eye to monitor cluster metrics in real to ensure normal service running. The supporte CSS metrics inclue the isk usage an cluster health status. You can learn about the isk usage of the cluster in a ly manner base on the isk usage metric. You can learn about the health status of a cluster base on the cluster health status metric. Clou Trace Service (CTS) With CTS, you can recor operations associate with CSS for later query, auit, an backtrack operations. Issue 01 ( ) Copyright Huawei Technologies Co., Lt. 7
