Announcement of "Oracle Cloud at Customer" service at Oracle CloudWorld

Today in Washington DC, USA, Oracle formally announced what it calls the "Oracle Cloud at Customer" service which, from my understanding, is a new term for the combination of Oracle hardware running in your data centre (see Oracle's Public Cloud Machine - initial thoughts and speculation), the Oracle public cloud software running on this hardware, and remote management by Oracle.

Note that, seemingly as of today, the new hardware is called the Oracle Cloud Machine (it was formerly known as "Oracle Public Cloud Machine" and "Oracle Private Cloud Machine for PaaS & IaaS"), abbreviated to OCM (no doubt to the chagrin of Oracle Certified Masters!).

Oracle had its top brass out today, with Thomas Kurian providing the primary keynote:

Very interestingly Oracle is clearly steering the conversation away from hardware altogether - there was very little mention of specifications and nothing about performance (which we usually hear for Engineered Systems) - this launch was primarily centred on flexibility of service provision.

Oracle's Public Cloud Machine - initial thoughts and speculation

One of the big announcements, or at least to me(!), at Oracle OpenWorld (OOW15) last October was what is now called the "Public Cloud Machine" (PCM). 

Here I've finally written up my initial thoughts on this machine and where it might be useful in modern Oracle infrastructures. All of the information I'm sharing here has either been said publicly by Oracle or else is my own personal speculation - please don't make any planning decisions until Oracle has released more details!

Note: I'm pleased to see that the name of this hardware has changed in the last few weeks from the "Private Cloud Machine for PaaS & IaaS" to the, much more snappy, "Public Cloud Machine" (PCM). Now you could say that running Oracle cloud platforms on your own premises makes it private cloud, but I can see the logic that says that it's a machine for running vanilla Oracle Public Cloud services. Primarily I suspect Oracle tweaked the name to try to reduce confusion with the Private Cloud Appliance (which was renamed from the Virtual Compute Appliance only last summer, rather unfortunately as it has turned out).

Update 24/3/16: this machine has been renamed to the Oracle Cloud Machine (OCM) - see Announcement of "Oracle Cloud at Customer" service at Oracle CloudWorld.

Firstly, let's look at what Oracle has said about the PCM so far...

What was the "Mandatory Maintenance for Java Cloud Service" last night?

Had I been working in Operations and on-call at an organisation using Java Cloud Service then it appeared I may well have been rudely woken up last night!  

At around 2am in the UK this email innocently dropped into my mail box:

Upcoming Mandatory Maintenance notification

This warning of an impending outage to Java Cloud Service was closely followed by one for Database Cloud Service. Judging by the email - "during the maintenance your services will be unavailable" - it seems an hour and a half later the instance failure notifications (from Enterprise Manager or Nagios etc) would have probably started coming in.

Then at 4:36am I had an email to say my JCS was now available again, and 5:11am to say my DBCS was too so, a total outage according to the emails of just under 2 hours. However when it happened all of my Java and Database test instances (test) were down already but as far as I can tell no changes were actually made to them (they were not started up for example) - be sure to read my conclusions at the end of this post!

SOA Cloud Service - initial impressions for SOA architects and administrators

Yesterday Oracle officially released their SOA Cloud Service (SOA-CS) - see the SOA team's blog post. As with Java Cloud Service (JCS) back in May I thought I'd write up my initial impressions, based on what I've learned so far about SOA-CS "on paper" and drawing on quite lot of hands-on experimentation with JCS.[Read More]

Java Cloud Service - detailed observations

I've been working with Oracle's full Java Cloud Service (JCS) for the past couple of months so thought this might be a good time to share a few observations, This blog post is mostly an informal list of observations and experiences - I am gradually refining my ideas into proper articles and presentations which I will publish over the coming months.JCS
