The FinOps Lifecycle - Three Phases of FinOps

The FinOps Lifecycle - Three Phases of FinOps 

Inform

Gain the visibility you need for cloud spend allocation. This helps create shared accountability within your business by showing teams what they are spending and why.

Optimize

Empower your teams by providing actionable recommendations. This helps teams identify, execute and measure efficiency optimizations.

Operate

Build governance policies that provide continuity and structure. This enables the goals of Technology, Finance and Business to be jointly achieved.

Increase Disk Size And Volume In VMware Linux VM

Increase Disk Size And Volume In VMware Linux Server 

APPLIES TO :  Linux VM running in VMware virtualization platform

ISSUE :  Linux volume running our of space. 

GOAL :  Increase the disk size and increase the volume size in Linux without adding new disk to VG

SOLUTION :  Increase the disk size in VMware settings, scan the disk and resize the volume.

Prerequisites :   NA

The server is having 35GB disk in VG01.

In Linux OS the disk size:

[root@test ~]#  fdisk -l|grep -i "/dev/sd"

[root@test ~]#  pvdisplay

Increase the disk size in VMware settings:

Scan the disk:

[root@test ~]#  ls /sys/class/scsi_disk/
0:0:0:0  0:0:1:0
[root@test ~]#  


[root@test ~]# echo "1" > /sys/class/scsi_disk/0:0:1:0/device/rescan

The disk size is increased:

[root@test ~]#  fdisk -l|grep -i "/dev/sd"

pvresize command will bring the disk space in VG:

[root@test ~]#  pvresize /dev/sdb

[root@test ~]#  pvdisplay

Free space is available in VG and you can increase the volume size:

[root@test ~]#  lvextend -r -L+10GB /dev/mapper/vg01-test

[root@test ~]#  df -h /test

OR 

lvextend -r -l +4608(Free PE) /dev/mapper/vg01-test - This will extend the complete free space to volume

Google Cloud Network Service Tiers : Premium Tier and Standard Tier

Network Service Tiers

Google Cloud is the first major public cloud to offer a tiered cloud network. 

Google Cloud is the first major public cloud to offer a tiered cloud network. 

Two tiers are available: 

1. Premium Tier

2. Standard Tier

Premium Tier:

Premium Tier delivers traffic from external systems to Google Cloud resources by using Google's highly reliable, low-latency global network. This network consists of an extensive private fiber network with over 100 points of presence (PoPs) around the globe. This network is designed to tolerate multiple failures and disruptions while still delivering traffic.

Premium Tier supports both regional external IP addresses and global external IP addresses for VM instances and load balancers. All global external IP addresses must use Premium Tier. Applications that require high performance and availability, such as those that use HTTP(S), TCP proxy, or SSL proxy load balancers with backends in more than one region, require Premium Tier. Premium Tier is ideal for customers with users in multiple locations worldwide who need the best network performance and reliability.

With Premium Tier, incoming traffic from the internet enters Google's high-performance network at the PoP closest to the sending system. Within the Google network, traffic is routed from that PoP to the VM in your Virtual Private Cloud (VPC) network or closest Cloud Storage bucket. Outbound traffic is sent through the network, exiting at the PoP closest to its destination. This routing method minimizes congestion and maximizes performance by reducing the number of hops between end users and the PoPs closest to them.

Standard Tier:

Standard Tier delivers traffic from external systems to Google Cloud resources by routing it over the internet. It leverages the double redundancy of Google's network only up to the point where a Google data center connects to a peering PoP. Packets that leave the Google network are delivered using the public internet and are subject to the reliability of intervening transit providers and ISPs. Standard Tier provides network quality and reliability comparable to that of other cloud providers.

Regional external IP addresses can use either Premium Tier or Standard Tier. Standard Tier is priced lower than Premium Tier because traffic from systems on the internet is routed over transit (ISP) networks before being sent to VMs in your VPC network or regional Cloud Storage buckets. Standard Tier outbound traffic normally exits Google's network from the same region used by the sending VM or Cloud Storage bucket, regardless of its destination. In rare cases, such as during a network event, traffic might not be able to travel out the closest exit and might be sent out another exit, perhaps in another region.

Standard Tier offers a lower-cost alternative for applications that are not latency or performance sensitive. It is also good for use cases where deploying VM instances or using Cloud Storage in a single region can work.
