Support local routing in transit gateway when PowerVS and VPC are from same region #1763
Comments
what's the different amount for these settings?
|
Need to add an additional flag to this spec here like routing - global/local
|
Still need to investigate that, will run two transit gateways with local and global routing for a couple of days and come back with the cost here! |
Just created this issue as a placeholder, in case if we are fixing it in hypershift, we can fix here too. |
Hey @dharaneeshvrd FYI, you can model it based on the cost estimator. https://www.ibm.com/cloud/cloud-calculator Thanks, Paul |
Thanks @prb112 for the link! Seems global routing costs double than the local routing for data transfer per GB. So it's better to use local routing in possible situations. Other thing I found is that reusing transit gateway also could save some dollars, it costs separately whenever we create and establish new a connection. If we can reuse the existing transit gateways with the combination of PowerVS and VPC that would save some $ as well. This would help in avoid creating multiple TGs during development phases. |

I think if user provided PowerVS zone and vpc.Region are within same region we can by default go for local routing and introduce a new field in api to allow user to configure it to use global. |
This needs:
@Karthik-K-N @dharaneeshvrd feel free to add If I'm missing something |
Do we really need a param to set the route? Not sure in which case user needs it, can't we just decide local or global based on the powervs and vpc region? What's the point in setting global routing even in cases where it only needs local routing? |
Its always good to give option for user to override, they can set it explicitly for any specific scenario. |

Describe the solution you'd like
[A clear and concise description of what you want to happen.]
Currently global routing is enabled by default, would like to enable local routing when PowerVS and VPC are from same region. This will reduce some $$$
