Amazon’s Elastic Beanstalk auto-scales your cloud application

1 Comment

Amazon has announced Elastic Beanstalk, which lets you deploy an application to Amazon’s EC2 (Elastic Compute Cloud) and have it scale up or down, by launching or terminating server instances, according to demand. There is no additional cost for using Elastic Beanstalk; you are charged for the instances you use.

Here is a dialog from the control console that says a lot about how the new service works:

image

As you can see, you can specify both a minimum and a maximum instance count, where the number is between 1 and 10,000. You can also control the “Trigger”, the metric that makes Elastic Beanstalk create or terminate instances.

Currently Elastic Beanstalk is for Java applications running on the Apache Tomcat application server, on a standard Amazon Linux virtual machine. However, the following comment in the FAQ indicates that Amazon is investigating other platforms:

Yes. Elastic Beanstalk is designed so that it can be extended to support multiple development stacks and programming languages in the future.

The innovation here is not so much in the technology, which stiches together a number of existing services, but rather in how easy and cheap it is to get started. The cost of entry is almost nothing; in fact, Amazon says you can run Elastic Beanstalk on its free usage tier, for a low-use application. Even I you expect it to remain low-use Elastic Beanstalk provides some other useful features like health monitoring.

It seems to me that this new service is cloud deployment as it should be: removing the administrative burden of scaling your application according to demand. Other platforms like Google App Engine also do this, but with more restrictions on how you design your application. Platforms like Microsoft Windows Azure let you scale your application, but you have to log into the console and spin instances up or down yourself.

One final observation: despite considerable unhappiness in the Java community about the way Oracle is managing the platform, there are still excellent reasons to use it, and Amazon has just provided one more.

iPhone plus Amazon app = shopping revolution through magic of barcode scanning

Amazon has added barcode scanning to its Apple iPhone shopping app. It is an amazing feature. Here’s why.

Among the questions that shoppers ask themselves, two of the biggest ones are first, is it any good; and second, is it good value? Barcode scanning helps with both of these. The scenario is that you are in the shop looking at a book, CD or DVD – or almost anything really, from kettles to MP3 players – and you wave your iPhone over it. Up comes the entry for that item in Amazon’s store, where you can see the rating, read customer reviews, and check the price both new and used.

OK, there is a little bit more involved than waving the iPhone, but not much. Here is how it works. Tap the Amazon app on the iPhone, then Search.

Tap Scan a barcode and hold the iPhone over the barcode.

image

You adjust the size and position by moving the iPhone until the code is roughly central between the guide lines. At this point, the guide lines turn green.

image

No need to tap; the app will now look up the item and show you the results. Tap the right-pointing arrow for more detail.

Confession: I am sufficiently an Amazon addict that I have done this in shops even before the advent of the barcode feature. One reason is price-checking. We all know that you pay a premium for the instant gratification of bricks and mortar shopping; but how bad is it? This will tell you instantly.

That might not help if you need a gift at the last minute, but the reviews might. I use this for video games, or for CDs that I have not heard or DVDs/Blu-rays that I have not seen. It has saved me from some expensive mistakes.

Of course reviews are subjective and some are likely planted by publishers, authors or competitors; but there are usually enough to give you some idea of the range of opinions.

It is also handy for electronic devices. Is that MP3 player any good? How does that iPod dock sound?

When I was at school we learned about the concept of perfect competition. One of the requirements for perfect competition is perfect information – for example, knowing the price charged for an item in every outlet which sells it. We are a long way from that, but thanks to the Amazon marketplace, where third-party sellers compete, we are closer than we were. The barcode feature in the Amazon iPhone app makes it easy to access that information while shopping, which is a big feature.

Database.com extends the salesforce.com platform

4 Comments

At Dreamforce today Salesforce.com announced its latest platform venture: Database.com. Salesforce.com is built on an Oracle database with various custom optimizations; and database.com now exposes this as a generic cloud database which can be accessed from a variety of languages – Java, .NET, Ruby and PHP – and accessed from applications running on almost any platform: VMForce, Smartphones, Amazon EC2, Google App Engine, Microsoft Azure, Microsoft Excel, Adobe Flash/Flex and others. One way to use it would via JPA (Java Persistence API) in an VMForce Java application.

The Database.com console is a web application that has a console giving access to your databases and showing useful statistics and system information.

You can also create new databases, specifying the schema and relationships.

The details presented in the keynote today were sketchy – we saw applications that honestly could have been built just as easily with MySQL – but there is more information in the FAQ. The Database.com API is through SOAP or REST web services, not SQL. Third parties can create drivers so you can you use it with SQL APIs such as ODBC or JDBC. There is row level security, and built-in full text search.

According to the FAQ, Database.com “includes a native trigger and stored procedure language”.

Pricing starts from free – for up to 100,000 records, 50,000 transactions and 3 users per month. After than it is $10.00 per month per additional 100,000 records, $10.00 per month per additional 150,000 transactions, and $10.00 per user if you need the built-in authentication and security system – which as you would expect is based on the native force.com identity system.

As far as I can tell one of the goals of Database.com – and also the forthcoming chatter.com free public collaboration service – is to draw users towards the force.com platform.

Roger Jennings has analysed the pricing and reckons that Database.com is much more expensive than Microsoft’s SQL Azure – for 500 users and a 50GB database $15,000 per month for Database.com vs a little over $500 for the same thing on SQL Azure, though the two are difficult to compare directly and he has had to make a number of assumptions. Responding to a question at the press and analyst Q&A today, Benioff seemed to accept that the pricing is relatively high, but justified in his view by the range of services on offer. Of course the pricing could change if it proves uncompetitive.

Unlike SQL Azure, Database.com starts from free, which is a great attraction for developers interested in giving it a try. Trying out Azure is risky because if you leave a service running inadvertently you may run up a big bill.

In practice SQL Azure is likely to be more attractive than Database.com for its core market, existing Microsoft-platform developers. Microsoft experimented with a web services API for SQL Server Data Services in Azure, but ended up offering full SQL, enabling developers to continue working in familiar ways.

Equally, Force.com developers will like Database.com and its integration with the force.com platform.

Some of what Database.com can do is already available through force.com and I am not sure how the pricing looks for organizations that are already big salesforce.com users; I hope to find out more soon.

What is interesting here is the way salesforce.com is making its platform more generic. There will be more force.com announcements tomorrow and I expect to to see further efforts to broaden the platform then.

Update – I had a chat with Database.com General Manager Igor Tsyganskiy. He says Microsoft’s SQL Azure is the closest competitor to Database.com but argues that because Salesforce.com is extending its platform in an organic way it will do a better job than Microsoft which has built a cloud platform from scratch. We did not address the pricing comparison directly, but Tsyganskiy says that existing Force.com customers always have the option to “talk to their Account Executive” so there could be flexibility.

Since Database.com is in one sense the same as Force.com, the API is similar. The underlying query language is SOQL – the Salesforce Object Query Language which is based on SQL SELECT though with limitations. The language for stored procedures and triggers is Apex. SQL drivers from Progress Software are intended to address the demand for SQL access.

I mentioned that Microsoft came under pressure to replace its web services API for SQL Server Data Services with full SQL – might Database.com face similar pressure? We’ll see, said Tsyganskiy. The case is not entirely parallel. SQL Server is a cloud implementation of an existing SQL database with which developers are familiar. Database.com on the other hand abstracts the underlying data store – although Salesforce.com is an Oracle customer, Tsyganskiy said that the platform stores data in a variety of ways so should not be thought of as a wrapper for an Oracle database server.

Although Database.com is designed to be used from anywhere, I’d guess that Java running on VMForce with JPA, and following today’s announcement Heroku apps also hosted by Salesforce.com, will be the most common scenarios for complex applications.

Now you can rent GPU computing from Amazon

1 Comment

I wrote back in September about why programming the GPU is going mainstream. That’s even more the case today, with Amazon’s announcement of a Cluster GPU instance for the Elastic Compute Cloud. It is also a vote of confidence for NVIDIA’s CUDA architecture. Each Cluster GPU instance has two NVIDIA Tesla M2050 GPUs installed and costs $2.10 per hour. If one GPU instance is not enough, you can use up to 8 by default, with more available on request.

GPU programming in the cloud makes sense in cases where you need the performance of a super-computer, but not very often. It could also enable some powerful mobile applications, maybe in financial analysis, or image manipulation, where you use a mobile device to input data and view the results, but cloud processing to do the heavy lifting.

One of the ideas I discussed with someone from Adobe at the NVIDIA GPU conference was to integrate a cloud processing service with PhotoShop, so you could send an image to the cloud, have some transformative magic done, and receive the processed image back.

The snag with this approach is that in many cases you have to shift a lot of data back and forth, which means you need a lot of bandwidth available before it makes sense. Still, Amazon has now provided the infrastructure to make processing as a service easy to offer. It is now over to the rest of us to find interesting ways to use it.

Stats that matter: Android grows in mobile, IE stops declining, eBooks take off

2 Comments

This should be three blog posts; but you’ve read this news elsewhere. Still, I can’t resist a brief comment on three recent trends.

Browsers

The first is that usage of Microsoft’s Internet Explorer has levelled off after a long period of decline. Microsoft says it is increasing but the numbers are too small to say that with confidence. StatCounter global stats for May to July show slight decline for IE (52.83% –> 52.37%) and FireFox (31.54%->30.88%), with Google Chrome the main beneficiary (8.81%->10.32%).

On this blog Chrome has grown from 4.2% to 12.4% in the last year. IE is still declining: 44.9% in July 09, 39.6% in June 10, and 38.2% in July 10.

My guess is that the success of Windows 7 might have brought back a few FireFox users. The interesting story though is where Chrome will be when it stops growing its share. My second guess is that it will be ahead of FireFox, though that is speculative. It is WebKit though, and I think that will be bigger than Mozilla’s Gecko thanks to adoption by Google, Apple, Adobe and others.

Mobile

Next, Google Android. Nielsen reports that it has pulled ahead of Apple iPhone in the US SmartPhone market; both are behind RIM’s Blackberry though that is in steady decline. RIM is announcing Blackberry 9800, the first on OS 6, later today; but I doubt it will disrupt Android’s growth. The developer angle is that Android is now equal to Apple’s iPad/iPhone in strategic importance, which will be a relief to Adobe – Flash runs on Android but not iPhone.

Android owners lack the satisfaction of Apple iPhone owners. 21% of them are eyeing the iPhone for their next upgrade, whereas only 6% of iPhone owners want Android next. Only 42% of Blackberry owners intend to remain loyal. It is all tending to confirm my speculation back in April that Android is the new Windows.

So in two years time, what will be the market share for RIM, Nokia Symbian/MeeGo, Windows Phone, HP Palm WebOS? It will not be easy for any of them.

eBooks

Finally, eBooks. The Kindle vs iPad vs Nook vs Sony is one story; but the bigger one is that the eBook is happening at last. David Carnoy’s recent articles on Amazon give the background. One is an interview with Amazon’s Ian Freed in which the retailer says eBook sales have tripled in the first quarter of 2010 vs that in 2009, and claims 70-80% of the market. Another looks at what Amazon didn’t say. However the market shares work out though, what matters is that screen, battery and wireless technology are now good enough, and publishers and authors willing enough, for eBooks to become mainstream, with huge implications for the media industry.

New Amazon Kindle with WebKit browser and free 3G internet

68 Comments

Never mind the books. Amazon’s new Kindle reader is offering as an “experimental feature” a web browser based on WebKit – the same engine as Apple Safari and Google Chrome – that is free to use over 3G networks:

New WebKit-Based Browser
Kindle’s new web browser is based on WebKit to provide a better web browsing experience. Now it’s easier than ever to find the information you’re looking for right from your Kindle. Experimental web browsing is free to use over 3G or Wi-Fi.

Amazon pays for the 3G coverage which is available globally. OK, it is monochrome, but since the Kindle also has a neat little keyboard is this now a great deal for blogging, checking Google maps, and so on?

image

Maybe not. Here’s what the terms and conditions say:

Use of Wireless Connectivity. Your Kindle uses wireless connectivity to allow you to shop for and download Digital Content from the Kindle Store. In general, we do not charge you for this use of wireless connectivity … You may use the wireless connectivity provided by us only in connection with the Service. You may not use the wireless connectivity for any other purpose.

If you are like me you may feel there is some inconsistency between these two statements. Enough to say that from my point of view free global web browsing would be a big incentive to purchase a Kindle; but I suspect that if this is real and turns out to be a popular feature consuming significant data traffic, Amazon will soon find a way to charge for it or turn it off.

It is also interesting to see a smidgen of convergence between the Kindle and more general-purpose slate devices. I am not sure if the Kindle strictly counts as a slate since it has a keyboard, but it certainly has the slate look and feel.

OpenStack takes on Amazon with open source cloud computing

2 Comments

Today’s big open source announcement is OpenStack, an open source cloud platform that aims to be an non-proprietary alternative to Amazon’s Elastic Computer Cloud (EC2) and Simple Storage Service (S3).

There are nearly 30 companies currently signed up to support OpenStack, including NASA, Citrix, Dell, Intel, AMD and Right Scale, but the big mover here is Rackspace, which says:

On July 19, 2010, we announced that we are opening the code on our cloud infrastructure. That’s big news for us and for the hosting industry in general. The result? Cloud technology will never look back.

The full press release is here. The initial offering is a distributed object store and a virtual machine provisioning engine.

OpenStack is not itself a cloud provider. Rather, it is offering software that lets you build a cloud, either for public or private use. Therefore, it is of immediate use only to large organisations, though for smaller users it might make sense to purchase services from an OpenStack provider since you are protected against lock-in.

The OpenStack cloud is IAAS – infrastructure as a service – offering storage and virtual machine instances. Therefore it is going up against Amazon rather than, say, Salesforce.com or Google App Engine. It is also an open source alternative to Microsoft Azure, which is also available (or will be) for both public and private clouds.

Looking at Right Scale’s comment, it seems that concern about Amazon taking over this market is a key driver behind the initiative:

From the RightScale perspective we will of course continue to support a variety of public and private clouds. We already have basic support for RackSpace’s API, which OpenStack will start out with, and we have a number of implementations under way with Eucalyptus and Cloud.com which we’re looking forward to multiply. At the same time, having many fragmented cloud efforts doesn’t really help build a compelling alternative to Amazon which keep adding incredible new features at a blazing pace. And the industry needs an alternative to Amazon, not because of some problem with AWS, but because in the long run cloud computing cannot fulfill its promise to revolutionizing the way computing is consumed if there aren’t a multitude of vendors with offerings targeting different use-cases, different needs, different budgets, different customer segments, etc. OpenStack promises to build enough momentum to create an exciting cloud offering that is as feature rich as AWS, that is implemented by a number of service providers, like RackSpace, and that enterprises can also run internally, like NASA.

For more information see the OpenStack site.

Adobe no longer investing in Flash compiler for iPhone, sings Android praises

4 Comments

Adobe’s Mike Chambers has posted about Apple’s new restriction on how applications are built for the iPhone or iPad. He says Adobe is ceasing development work on this feature:

We will still be shipping the ability to target the iPhone and iPad in Flash CS5. However, we are not currently planning any additional investments in that feature.

Of course he says “currently” so development could be resumed, presumably if the restriction is lifted.

He also suggests that Apple may be specifically targeting Flash despite the general wording of its notorious clause 3.3.1:

While it appears that Apple may selectively enforce the terms, it is our belief that Apple will enforce those terms as they apply to content created with Flash CS5.

Chambers spends much of his post saying how well Flash runs on Android – though Flash Player 10.1 and AIR 2.0 for Android are still in beta – and suggesting that Flash developers target Android instead.

The problem is that developers will go where their customers are. If Apple continues to increase its market share, its platform will continue to attract developers.

This is another instance of something I blogged about two years ago: the risk of building your business on a third-party platform. My post then was about Amazon, eBay and Facebook. Now the focus is on Apple. Other platforms like Salesforce.com and Google have the same inherent problem.

I think this problem will get worse rather than better, as people migrate from general-purpose open platforms to more locked-down appliances.

Google storage 10 times cheaper than Azure – but not as cheap as Skydrive

According to Jerry Huang of Gladinet, whose Cloud Desktop exposes a variety of cloud storage services as mapped drives in Windows Explorer, Google storage is “about 10 times cheaper” than Windows Azure. Since Amazon S3 has similar prices to Azure, I imagine Google undercuts that by some margin as well.

Gladinet compares Google and Azure using some other criteria as well. On speed, it gave the edge to Azure but observed that it might just depend which data center was nearest. On SLA, the two seem similar.  On API, it says Azure is easier if you use Visual Studio, but not if you work with “PHP, Ruby or anything other than .NET”.

In another post, Huang has a nice summary of accessing Azure storage from C#.

It’s worth noting that Microsoft Skydrive offers a relatively generous 25GB of storage for free, but there is no way to extend this limit.  There is also no official Skydrive API, though one has been hacked unofficially. Gladinet supports Skydrive too, using either this or the unofficial WebDAV support.

I am a fan of Gladinet. There is a free starter edition, or paid-for with extra features.

Explorer integration is a big deal, since it means any application with a standard open or save dialog can access the files. Imagine for example that you need to upload a document from cloud storage to a web site. Without Explorer integration, you have to extract the file from cloud storage to your local drive, then upload it from there. The same is true of SharePoint, which is why it is unfortunate that Explorer integration is so difficult to get working.

Amazon gives in to Macmillan thanks to power of Apple

In a posting on its forum, Amazon has declared defeat in its disagreement with Macmillan over ebook terms – one most likely influenced by Apple which is offering better terms to publishers for its forthcoming iPad:

Macmillan, one of the "big six" publishers, has clearly communicated to us that, regardless of our viewpoint, they are committed to switching to an agency model and charging $12.99 to $14.99 for e-book versions of bestsellers and most hardcover releases.

We have expressed our strong disagreement and the seriousness of our disagreement by temporarily ceasing the sale of all Macmillan titles. We want you to know that ultimately, however, we will have to capitulate and accept Macmillan’s terms because Macmillan has a monopoly over their own titles, and we will want to offer them to you even at prices we believe are needlessly high for e-books. Amazon customers will at that point decide for themselves whether they believe it’s reasonable to pay $14.99 for a bestselling e-book. We don’t believe that all of the major publishers will take the same route as Macmillan. And we know for sure that many independent presses and self-published authors will see this as an opportunity to provide attractively priced e-books as an alternative.

While Amazon is focusing on the higher price, what really counts here is who sets the price and how much money goes back to the publisher. It’s not clear to me why any publisher would not do the same as Macmillan, since it is to their advantage.

I am surprised Amazon gave in so easily. Its PR has has been clumsy – first, to withdraw titles from sale thus ensuring strong opposition from frustrated authors, and coming over as a bully; and second, to state so clearly, early in the battle, that “we will have to capitulate” – not language you normally hear from a major corporation.

It is evidence of Apple’s extraordinary power to disrupt markets.

If you missed the background, see yesterday’s post.
