Transit VPC Google cloud networks - All you need to know ?

This article covers an overview of Transit VPC Google cloud networks. In fact, transit connectivity is a solution where we can connect a network with multiple peered networks, it can act as a centralize transit hub through which we can route traffic to multiple VPCs together so it will save overall cost to set up multiple VPNs between networks.

VPC Network Peering is useful in these environments:

• SaaS (Software-as-a-Service) ecosystems in Google Cloud. You can make services available privately across different VPC networks within and across organizations.
• Organizations that have several network administrative domains that need to communicate using internal IP addresses.

Using DigitalOcean Droplet on PuTTY ssh client

This article covers how to use Putty on the Digitalocean platform. In fact, DigitalOcean Droplets are Linux-based virtual machines (VMs) that run on top of virtualized hardware. Each Droplet you create is a new server you can use, either standalone or as part of a larger, cloud-based infrastructure.

How to Destroy a Droplet from the DigitalOcean Control Panel ?

Deleting a Droplet permanently and irreversibly destroys the Droplet and its contents, and its automated backups. Optionally, you can also destroy a Droplet and its associated snapshots, volumes, and volume snapshots. 

• To save one or more of the backup images, convert the backup into a snapshot before deleting the Droplet.
• To destroy a Droplet from the control panel, open the Droplet's More menu and click Destroy. Alternately, you can click the Droplet's name to access its main page and select Destroy from the left menu.
• On the Destroy page, there are two headings: Destroy Droplet and backups and Rebuild Droplet. Under Destroy Droplet and backups, you can choose to destroy the Droplet and its backups. If the Droplet has associated resources, you can also choose to delete some or all of them, but they are not destroyed by default.
• If you wish to retain a backup, you must convert it to a snapshot before deleting it. Any associated reserved IP addresses, load balancers, or firewalls still need to be deleted individually.
