This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
VPC Peering vs Transit Gateway writes how many networks you administer and who would own the transit point. You do not attach a network you do not run. A cost figure you type is an estimate.
Write the account, project, or repository you administer, the name of this change, and the time. A second change waits until this line has been read back.
The browser tool drafts text or reads a paste you already hold. It does not log in, it does not scan, and it does not apply.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced.
The change you can finish
Apply nothing while you are writing the note. When the lab window opens, it is one change on the account named in the ticket. Read the draft, then the account, then decide.
Rollback is the previous file, the previous plan, or the lab resource you can delete because it was only a lab.
- Write the networks you administer.
- Write both options in one sentence each.
- Mark the owner of a transit point.
- Do not create a peering or a gateway.
- Label any price an estimate.
- Stop.
Mistakes that outlive the statement
VPC Peering vs Transit Gateway goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- A gateway created during the reading.
- A network you do not administer attached in the note as if it were done.
- An estimate treated as a bill.
- 0.0.0.0/0 written as the allowed path.
Decisions to write down
One decision for VPC Peering vs Transit Gateway: The networks are yours. Nothing is created. The price is an estimate. The allowed path is narrow. And one comparison is enough.
Checks before you call it done
Confirm this before you call the change done: The networks are written. Nothing was created. The estimate is labelled. 0.0.0.0/0 is not the design. And a second person can say which option is only a note. If one of those fails, stop.
# Peering note. Do not create a gateway during the reading.
Before you leave the account
VPC Peering vs Transit Gateway ends when the account in the note is the account in the ticket. If it is not, stop.
The draft stays a draft until a person has read the names in it. A generator does not log in, does not apply, and does not scan.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep. 10.0.0.0/16 is a sample prefix, not a network you publish unless you already use it.
prompt-for-this is a reminder that a secret is missing. It is not an access key, a token, or a password you save. An Azure secret draft may contain a sample password. Replace it. Do not file it.
One change is the window. If two things move and the result is wrong, you will not know which one did it.
If the same step fails twice, stop for the day. Restore the copy you took first.
A second person reads the account and the change aloud. If they cannot find them in the ticket, the note is not done.
This page is a planning guide. It is not a vendor manual, not an official standard, not legal advice, and not an audit opinion. You do not apply it against an account you do not administer.
