| |
| − | == pricing ==
| |
| − | For this example of '''Google Cloud Computing''', we wan't to have access to as many computer cores as possible
| |
| − |
| |
| − | * The pricing explained here: https://cloud.google.com/pricing/
| |
| − | * A pricing calculator is here: https://cloud.google.com/products/calculator/
| |
| − |
| |
| − | '''For the price calculation of:'''
| |
| − | * '''1''' server
| |
| − | * using '''Free: Debian, CentOS, ...'''
| |
| − | * with a '''regular''' VM Class
| |
| − | * Instance type of (HIGH CPU) '''n1-highcpu-32 (vCPUs: 32, RAM: 28.80 GB)'''
| |
| − | * 0 '''SSD'''
| |
| − | * Datacenter location '''Europe'''
| |
| − | * Average days per month each server is running: '''1''' days, per month.
| |
| − | The '''monthly''' price was of November 2015, '''$32.26'''.
| |
| − |
| |
| − | At November 2015, google give free trial of '''300$'''. https://cloud.google.com/free-trial/
| |
| − |
| |
| − | Note, there are some limitations: https://cloud.google.com/free-trial/#/faq
| |
| − |
| |
| − | == Start free trial ==
| |
| − | Please first see this video:
| |
| − | * https://cloud.google.com/compute/docs/linux-quickstart or https://www.youtube.com/watch?v=BnEhYaUY4sA
| |
| − |
| |
| − | Go to: https://cloud.google.com/free-trial/ and click '''Start your free trial'''.
| |
| − |
| |
| − | You need to sign up with a credit card. To prevent mis-abuse from robots and hackers.
| |
| − |
| |
| − | '''Then go to: https://console.developers.google.com'''
| |
| − | * You should already have a project called '''My First Project'''.
| |
| − | * '''Create a new project''' in top right corner of the browser under the dropdown of '''My First Project'''.
| |
| − | * Call the new project '''relax''' with '''App Engine location''' at '''europe-west'''
| |
| − |
| |
| − | == Create a Virtual Machine instance ==
| |
| − | * Click then at '''Try Compute Engine''' or go to https://console.developers.google.com/compute
| |
| − | * Click '''Create instance'''
| |
| − | * '''Name:''' relax
| |
| − | * '''Zone:''' Don't change this. As of Nov 2015, it seems that if you change this, you cannot select more than 2 vCPU's
| |
| − | * '''Machine type:''' From the very bottom, create '''8 vCPUs'''. 32 cores need an upgrade to you account, [https://cloud.google.com/free-trial/#/faq and the free trial only allows for 8 vCPU's.]
| |
| − | * '''Boot disk:''' 10 GB of Ubuntu 14.04 LTS
| |
| − | * '''Zone:''' Now change this to: europe-west1-c
| |
| − | * Let the rest be default and click '''Create'''.
| |
| − |
| |
| − | == Access Virtual Machine instance ==
| |
| − | * Go to https://console.developers.google.com/compute
| |
| − | * In the line of '''relax''', click '''SSH'''
| |
| − | * This should open a '''browser terminal window'''
