UltraStar have been very helpful in our cloud journey with them as they are one of few companies who can provide all 3 categories - public/hybrid clouds (AWS), private or hybrid clouds(Azure). Their team is knowledgeable and has helped us understand how Azure fits into their strategy. They also help you pick up things quickly by providing hands-on training sessions during your onboarding process so that we don't need much time after completing it before starting using azures features effectively. I would like if there was some way where customers could easily share problems which they were facing while working with UltraStar but unfortunately this isn't possible at present moment! In general everything about ultrashare worked really well till now. We use many different products from various vendors such as AWS Redshift etc., So its always good when someone comes along who understands multiple technologies and helps out.
