Amazon continue on their relentless march towards being the be-all and end-all of both IaaS and PaaS with this latest offering, which will leave the likes of SendGrid and Postmark somewhat ruffled. The new price point set by Amazon is $0.10 per thousand emails sent, with 2,000 emails a day included for free if you're on EC2's free usage tier.
Not all startups should use AWS as their host, but with every similar offering that Amazon adds to their line-up, the proposition becomes more enticing.
Amazon currently dominates the IaaS space. How long before they dominate PaaS too? Is there a space for pure PaaS vendors?
