Virtualized data centers
- IaaS (基礎架構作為服務) ：類似於資料中心
- Hybrid
- PaaS(platform as a service)：將程式代碼運算邏輯雲端化
- Serverless logic
- Automated elastic resources
GCP regions and zones
層級
- Multi-Region
- Region
- Zone
Zone定義
- zone doesn’t always correspond to a single physical building.
- All the zones within a region have fast network connectivity among them.
- Zones are grouped into regions, independent geographic areas
Virtual Private Cloud (VPC) Network
- have region and global scale
- If you increase the size of a subnet in a custom VPC network, the IP addresses of virtual machines already on that subnet might be affected.
Compute Engine
- virtual machine type
- standard
- SSD
- OS
- Preemptible VM:可以依據需求暫停虛擬機來節省花費
Cloud Load Balancing
is a fully distributed, software-defined managed service for all your traffic.
Google VPC networks and subnets
- networks : global scope
- subnets : regional scope
You can dynamically increase the size of a subnet in a custom network by expanding the range of IP addresses allocated to it. Doing that doesn’t affect already configured VMs.
consistent
- routing tables : forward traffic from one instance to another instance within the same network
- global distributed firewall : You can control to restrict access to instances, both incoming and outgoing traffic
Cloud Load Balancing options
a fully distributed, software-defined managed service for all your traffic.
- Global HTTP : can routr different URLs to different back ends
- GLobal SSL Proxy : Suppoerted on specific port numbers
- Global TCP Proxy : Supported on specific port numbers
- Regional : Supported on any port number
- Regional internal
VPC selection
VPC Peering : establish a peering relationship between two VPCs so that they can exchange traffic
Shared VPC : full power of IAM to control who and what in one project can interact with a VPC in another
Interconnection options
Peering traffic (traffic flowing between peered networks)
- VPN
- Direct Peering : 一對多的共用線路的連線，共享頻寬
- Carrier Peering
- Dedirected Interconnect : 建立與Google的加密直接連線,一對一
Cloud Storage: 一種object storage
Different applications and workloads required different storage database solutions
- 上傳後會被系統賦予一個唯一的索引值，並以buckets的形式儲存
- 用系統給予的唯一鍵值(key)來索引資料，url形式索引
- 不被歸類為File Syetem ★
- 檔案被上傳後是不可編輯的，但可以透過上傳功能來更新檔案
[x] 開啟版本管理：可以切換上傳的檔案版本
[ ] 沒打開版本管理：舊版會無條件被新版替代 - 在伺服器端會被自動加密且無須花費
- Access Control Lists : 提供尋找檔案權限管理
- Life cycle management policy :
- 排程檔案將被刪除的時間
- 篩選並刪除某一時間點上傳的檔案
- 篩選並留下最近上傳的檔案版本

APP Engine
Google Cloud Endpoints and Apigee Edge
Cloud Endpoints
- have a single coherent way for it to know which end user is making the call
- the backend services need be in GCP,
Apigee Edge
- focus on business problems like rate limiting, quotas, and analytics.
- the backend services need not be in GCP,
