Smalltalk as a dynamic language with environment which enables applications to grow organically (saying simpler: to be updated while running) has actually a big potential in the cloud. To provide web services via REST APIs to the so called front-end clients like mobile apps or client-side web apps. And yes, we have now adequate support for REST API services, including OpenID for authentication and OAuth for authorization. Maybe OpenID/OAuth server would be also nice.. You are probably aware of work by Gemstone guys, specially by James Foster, to put Smalltalk web app on the CloudFoundry [1]. This can be the start and their experiences adapting Gemstone to work in existing cloud infrastructure is valuable to tho the same with Pharo. I'd also go adapting Pharo to some existing cloud infrastructure like Amazon, Heroku, CloudFoudry, ... We seems to don't have enough resources to build and maintain our own ones, as experience with our hosting attempts so far shows. It would be also long-term better to join the cloud wave instead building our own replicas. Because a whole IT world goes that way.

he, sorry for insist, but cloudfoundry already does that... and is opensource too :) at ESUG I seen James present it to deploy pharo images... so is viable :) cheers, Esteban On Jan 26, 2013, at 1:52 PM, Andy Burnett <andy.burnett(a)knowinnovation.com> wrote: > <I am merging my responses to Bernat and Stephane> > > I agree that there are probably too few webdevs to make this viable - > yet :-).

<I am merging my responses to Bernat and Stephane> I agree that there are probably too few webdevs to make this viable - yet :-). However, we may be able to build on other people's work. For example, I have been quite impressed by OpenShift. I wondered if someone could create a Pharo (or gemstone) cartridge. That would then give us access to the rest if their system. It might then allow anyone to set up their own system, just by using that cartridge. Obviously, someone would need to keep the cartridge up to date etc, and maybe a first step would be to adapt the work on Harbour to make image uploading easier. At this point, as I am sure you can tell, I am way beyond my expertise, so I am just guessing. However, it does seem as though people - such as redhat - are doing a lot if the work for us, and it could be smart to build on their structures. Has anyone tried creating a cartridge? Or would someone like to try? I am happy to sponsor part of this, if that helps. Cheers Andy

Thanks for the bump in that direction. Your help is appreciated. Q: I just downloaded Pharo by Example, in an attempt to start somewhere... and at chapter 6.2 The Browser, the Kernel package seems to have changed entirely in Pharo 1.4. There are almost no similarities, from what i can gather it's been completely rewritten way beyond refactoring, the patterns are different. It's like being a two-eyed man in a dark room with no flashlight. Your eyes are there, but without the flashlight there might as well be no room.

Re: [Pharo-users] Phaas - anyone interested in setting up Pharo as a Service?

I'd be so happy if something like this existed. However, I'm not sure there are enough Pharo webdevs to make a service like that profitable... But yes, I do feel this need! I'm sick of configuring VPSes with their apache virtual hosts, DBs, etc. 2013/1/26 Andy Burnett <andy.burnett(a)knowinnovation.com> > We would love to develop more of our ideas in Pharo, but we are completely > allergic to doing sys admin.

Phaas - anyone interested in setting up Pharo as a Service?

by Andy Burnett

We would love to develop more of our ideas in Pharo, but we are completely allergic to doing sys admin. We don't want to deal with anything below the Pharo application level. What I would ideally like to see if something like Heroku, or similar, but for Pharo. However, just wishing won't make it happen, so I am wondering if there is anyone out there who is thinking about this, and whether there are enough of us to constitute are market. Our requirements are pretty simple. We need a way of uploading an image, and some standard for of persistence. At this point, we would be perfectly happy to make compromises by agreeing that it had to be e.g. Mongo or whatever (although ideally it would be gemstone). We just want to make some progress on this. Personally, I think lots of bits are coming together. We now have various persistence options, websockets (both in Zinc and Aida-web), OAuth ( in both places again), and lots of other exciting elements. We just want a really simple way to take advantage of them. Does anyone else feel this need?
