Note for Elasticsearch

名詞解釋

Relational DB -> Server -> Databases -> Schema -> Tables -> Rows -> Columns
Elasticsearch -> Node -> Indices -> Mapping -> Types  -> Documents -> Fields
  • 在 Elasticsearch 當中，每個儲存 Document 的動作我們稱之為 Indexing（索引）
  • Shard：通常叫做分片，這是 Elasticsearch 提供分散式搜尋的基礎，其含義是將一個完整的 Index 分成若干部分，儲存在相同或不同的 Node 上，這些組成 Index 的部分就叫做 Shard。
  • Replica：意思跟 Replication 差不多，就是 Shard 的備份，所以一個 Index 的 Shard 數量就等於 Shard × (1 + Replica)。
  • 映射(mapping)用於進行字段類型確認，將每個字段匹配為一種確定的數據類型(string, number, booleans, date等)。

Note for AWS VPC

Instructions of creating AWS VPC

  • Classes Inter-Domain Routing (CIDR) 用於給用戶分配 IP 位址以及在網際網路上有效地路由 IP 封包的對 IP 位址進行歸類的方法
  • CIDR 是一個按位，並且基於字首位數，用於解釋 IP 位址的標準
  • 假設有一 IP 位址為 A.B.C.D/N，斜線後面的數字 N 即為字首長度，也就是從左到右，被位址塊裡的位址所共享的位的數目。如果有一 IP 位址的前 N 位與一個 CIDR 位址塊的字首相同的話，那麼就說明這個 IP 位址屬於這個 CIDR 位址塊

The note of Amazon EC2

Amazon Elastic Compute Cloud(EC2)

Amazon Elastic Compute Cloud(EC2) is a web service that provide resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.

The simple interface makes us obtain and configure capacity with minimal friction

Verifying Region in the AWS console

Most of the Amazon Web Services offer a regional endpoint to the requests to reduce the data latency in the applications. An endpoints is a URL that is the entry point for a web service. You can choose multiple locations to place your EC2 instance on. Amazon EC2 locations are composed of regions that contain Availability Zone. Regions are located in seperate geographic areas (US, EU, etc.). Availability Zones are distinct locations within a region that are engineered to be isolated from failures in other Availability Zones and to provide
