Google Cloud Platform (GCP) Cloud Storage Product Overview Google Cloud Platform (GCP) Features Object storage (replace only), NOT a file store (cannot open an object for writing) Globally unique bucket names Max size of a single object is 5 TB Durability: 11 x 9's Object metadata Versioning: gsutil ls -a # to show all files, including all old versions of a file Lifecycle Management Lifecycle rules and actions - e.g. based on age, creation date, storage class then do an action, such as set it to nearline, coldline, delete it Change notifications - e.g. use Cloud Functions to do something with the object when it is uploladed etc Sharing files Signed URLs provide temporary access to storage buckets 1. Create key : ``` gcloud iam service-accounts keys create ~/key.json --iam-account storage-admin-sa@my-project.iam.gserviceaccount.com 2. Create signed url: ``` gsutil signurl -d 10m ~/key.json gs://my-secure-bucket/blah.jpg Static content Give 'allUsers' read access Access URL: https://storage.googleapis.com/bucketname/filename Map bucket to your domain GCP doco on static websites with Cloud Storage Name the bucket using your domain or subdomain name Point a CNAME record for your subdomain to c.storage.googleapis.com Prove ownership with a TXT record GCP doco for domain name verification Set option on the bucket "edit website configuration" to specify Main page and 404 page To serve as HTTPS Guidance on HTTPS serving Google doco on Firebase hosting, HTTPS and setting up a custom domain Create a load balancer (under Network Services) Backend config: point to your storage bucket, enable Cloud CDN optionally Frontend config: http or https protocol, provide a certificate (have Google create for free (Let's Encrypt) or upload own) Create A record to point to load balancer Request Pays capability - user is charged instead of you Bucket Lock Retention Policy - set a minimum duration to prevent modification or deletion of an object after it has been uploaded Event-based holds by default - places holds on objects as they are uploaded, preventing modification or deletion until you remove the hold - which then starts the clock for the retention policy Security Permissions Can add members - via email account or choose 'allusers' Can add a group, domain, user email, or project - and give read or owner permissions IAM Roles Storage Object Viewer - 4 permissions: get/list resourcemanager.projects and storage.objects Creator - 3 permissions: storage.objects.create, get/list resourcemanager.projects Admin - 9 permissions: storage.object.create/delete/get/getIamPolicy/list/setIamPolicy/update, resourcemanager.projects.get/list Settings to choose at creation of bucket Access Control model (choose at bucket creation) Set permissions uniformly at bucket-level (Bucket Policy Only) Set object-level and bucket-level permissions (more granular) Storage Classes GCP documentation on Storage Classes Standard Storage - no minimum storage duration Nearline Storage - min duration 30 days; generally cheaper than Standard if you access it less than once per month Coldline Storage - min duration 90 days; generally cheaper than Standard if you access it less than once per year Encryption Encrypted by default - Google managed key Customer managed key via Google Cloud Key Management Service (KMS) Customer supplied keys - created and managed by you and uploaded into GCP Set a retention policy: enter a duration of seconds/days/months/years Labels - key/value pairs Data Transfer Options For small amounts of data Web console upload gsutil: rsync multithreaded option; resumable in case of network interruption JSON API Storage Transfer Service Bucket to bucket Scheduled or ad hoc - create a transfer job, including from an S3 bucket BigQuery Data Transfer Service Import into BigQuery Transfer Appliance Transfer Appliance - physical hardware sent to you for offline data transfers Need to request a transfer appliance from Google You manage the encryption key Disk sizes: 100TB, 480TB Pricing Overview Pricing Tables GCP Doco Charges are pro-rated to the sub-second for each object (except Nearline and Coldline) Each object version is charged at same rate as the live version At-Rest Data Storage Pricing Regional: 99.9% availability; 2.3 cents / GB-month Standard, 1.6 cents Nearline, 0.06 cents Coldline Multi-region: 99.95% availability (US or Asia or Europe) - 5 out of 1000 requests fail; 2.6 cents / GB-month, 1 cent Nearline, 0.07 cents Coldline Dual-region: 99.95% availability (Iowa (middle US) and South Carolina (East US)); 3.6 cents / GB-month Standard, 2 cents Nearline, 0.09 cents Coldline Egress within GCP Pricing Within same location/zone, or between region to multiregion (or vice versa) services - Free Between different parts of continent - 1 cent/GB Between worldwide locations - see General Network usage pricing General Network Usage Pricing Monthly 0-1 TB - Aust-SE1 to: World 19 cents, China 23 cents;
