Scaling Your Application Efficiently – Horizontal or Vertical? #CloudWF

Guest Blog with AppDynamics

Author: Eric Smith at AppDynamics

Anyone deploying an application in production probably has some experience with scaling to meet increased demand. A generation ago, virtualization made scaling your application as simple as increasing your instance count or size. However, now with the advent of cloud, you can scale to theoretical infinity. Maybe you’ve even set up some auto-scaling based on underlying system metrics such as CPU, heap size, thread count, etc. Now the question changes from “Can I scale my environment to meet demand?” (if you add enough computing resources you probably can), to “How can I efficiently scale my infrastructure to accommodate my traffic, and if I’m lucky maybe even scale down when needed?” This is a problem I run into almost every day dealing with DevOps organizations.

If your application environment looks like this (if so, I’d love to be you):

You can probably work your way through to the solution, eventually. Run a bunch of load tests, find a sweet spot of machine size based on the performance under the test parameters, and bake it into your production infrastructure. Add more instances to each tier when your CPU usage gets high. Easy. What if your application looks like this?

Screen-Shot-2015-03-17-at-10.57.45-AM

What about when your application code changes? What if adding more instances no longer fixes your problem? (Those do cost money, and the bill adds up quickly…)

The complexity of the problem is that CPU bounding is only one aspect — most applications encounter a variety of bounds as they scale and they vary at each tier. CPU, memory, heap size, thread count, database connection pool, queue depth, etc. come into play from an infrastructure perspective. Ultimately, the problem breaks down to response time: how do I make each transaction as performant as possible while minimizing overhead?

The holy grail here is the ability to determine dynamically how to size my app server instances (right size), how many to create at each level (right scale) and when to create them (right time). Other factors come into play as well such as supporting infrastructure, code issues, and the database — but let’s leave that for another day.

Let me offer a simple example. This came into play recently when working with a customer analyzing their production environment. Looking at the application tier under light/normal load, it was difficult to determine what factors to scale, we ended up with this:

Screen-Shot-2015-03-17-at-10.57.54-AM

Response time actually decreases toward the beginning of the curve (possibly a caching effect?). But if you look at the application under heavier load, things get more interesting. All of a sudden you can start to see how performance is affected as demand on the application increases:

Screen-Shot-2015-03-17-at-10.58.02-AM

Looking at a period of heavy load in this specific application, hardware resources are actually still somewhat lightly utilized, even though response time starts to spike:

Screen-Shot-2015-03-17-at-10.58.12-AM
Screen-Shot-2015-03-17-at-10.58.24-AM

In this application, it appears that response time is actually more closely correlated with garbage collection than any specific hardware bound.

While there is clearly some future effort here to look at garbage collection optimization, in this case optimizing best fit actually comes down to determining desired response time, maximum load for a given instance size maintaining that response time, and cost for that instance size. In a cloud scenario, instance cost is typically fairly easy to determine. In this case, you can normalize this by calculating volume/(instance cost) at various instance sizes to determine a better sweet spot for vertical scale.

Horizontal scale will vary somewhat by environment, but this tends to be more linear — i.e. each additional instance adds incremental bandwidth to the application.

There’s still quite a bit more room for analysis of this problem, like resource cost for individual transactions, optimal response time vs. cost to achieve that response time, synchronous vs. asynchronous design trade-offs, etc. but these will vary based on the specific environment.

Using some of these performance indicators from the application itself (garbage collection, response time, connection pools, etc.) rather than infrastructure metrics, we were able to quickly and intelligently right size the cloud instances under the current application release as well as determine several areas for code optimization to help improve their overall efficiency. While the code optimization is a forward looking project, the scaling question was in response to a near term impending event that needed to be addressed. Answering the question in this way allowed us to meet both the near term impending deadline, but also remain flexible enough to accommodate any forthcoming optimizations or application changes.

To Cloud, or not to Cloud? #CloudWF

Source: Business Cloud News

To cloud or not to cloud? With the right strategy, it need not be the question.

There are two sides to the cloud coin: one positive, the other negative, and too many people focus on one at the expense of the other for a variety of reasons ranging from ignorance to wilful misdirection. But ultimately, success resides in embracing both sides and pulling together the capabilities of both enterprises and their suppliers to make the most of the positive and limit the negative.

Cloud services can either alleviate or compound the business challenges identified by Ovum’s annual ICT Enterprise Insights program, based on interviews with 6,500 senior IT executives. On the positive side both public and private clouds, and everything in between, help:

  • Boost ROI at various levels: From squeezing more utilization from the underlying infrastructure to making it easier to launch new projects with the extra resources exposed asa result.
  • Deal with the trauma of major organisational/ structural changes as they can adapt to the ups and downs of requirements evolution.
  • Improve customer/citizen experience, and therefore satisfaction: This has been one of the top drivers for cloud adoption. Cloud computing is at its heart user experience-centric. Unfortunately many forget this, preferring instead to approach cloud computing from a technical perspective.
  • Deal with security, security compliance, and regulatory compliance: An increasing number of companies acknowledge that public cloud security and compliance credentials are at least as good if not better than their own, particularly in a world where security and compliance challenges are evolving so rapidly. Similarly, private clouds require security to shift from reactive and static to proactive and dynamic security, whereby workloads and data need to be secured as they move in and out of internal IT’s boundaries.

On the other hand, cloud services have the potential to compound business challenges. For instance, the rise of public cloud adoption contributes to challenges related to increasing levels of outsourcing. It is all about relationship management, and therefore relates to another business challenge: improving supplier relationships.

In addition to having to adapt to new public cloud offerings (rather than the other way round), once the right contract is signed (another challenging task), enterprises need to pro-actively manage not only their use of the service but also their relationships with the service provider, if only to be able to keep up with their fast-evolving offerings.

Similarly, cloud computing adds to the age-old challenge of aligning business and IT at two levels: cloud-enabling IT, and cloud-centric business transformation.

From a cloud-enabling IT perspective, the challenge is to understand, manage, and bridge a variety of internal divides and convergences, including consumer versus enterprise IT, developers versus IT operations, and virtualisation ops people versus network and storage ops. As the pace of software delivery accelerates, developers and administrators need to not only to learn from and collaborate with one another, but also deliver the right user experience – not just the right business outcomes. Virtualisation ops people tend to be much more in favour than network and storage ops people of software-defined datacentre, storage, and networking (SDDC, SDS, SDN) with a view to increasingly take control of datacentre and network resources. But the storage and network ops people, however, are not so keen on letting the virtualisation people in.

When it comes to cloud-centric business transformation, IT is increasingly defined in terms of business outcomes within the context of its evolution from application siloes to standardised, shared, and metered IT resources, from a push to a pull provisioning model, and more importantly, from a cost centre to an innovation engine.

The challenge, then, is to understand, manage, and bridge a variety of internal divides and convergences including:

  • Outside-in (public clouds for green-field application development) versus inside-out (private cloud for legacy applicationmodernization) perspectives. Supporters of the two approaches can be found on both the business and IT sides of the enterprise.
  • Line-of-business executives (CFO, CMO, CSO) versus CIOs regarding cloud-related roles, budgets, and strategies: The up-andcoming role of chief digital officer (CDO) exemplifies the convergence between technology and business C-level executives. All CxOs can potentially fulfil this role, with CDOs increasingly regarded as “CEOs in waiting”. In this context, there is a tendency to describe the role as the object of a war between CIOs and other CxOs. But what digital enterprises need is not CxOs battling each other, but coordinating their IT investments and strategies. Easier said than done since, beyond the usual political struggles, there is a disparity between all side in terms of knowledge, priorities, and concerns.
  • Top executives versus middle management: Top executives who are broadly in favour of cloud computing in all its guises, versus middle management who are much less eager to take it on board, but need to be won over since they are critical to cloud strategy execution.
  • Shadow IT versus Official IT: Where IT acknowledges the benefits of Shadow IT (it makes an organisation more responsive and capable of delivering products and services that IT cannot currently support) and its shortcomings (in terms of costs, security, and lack of coordination, for example). However, too much focus on control at the expense of user experience and empowerment perpetuates shadow IT.

Exclusive Q&A with Fin Goulding, CIO of Paddy Power

fin2
Fin Goulding is Chief Information Officer at Irish bookmaker Paddy Power, and is speaking at Cloud World Forum at London’s Olympia on 24-25 June, about the Cloud and DevOps in his business. We took some time with Fin to talk about the challenges and status of Cloud in his sector, followed by an in-depth discussion on what DevOps means to him personally.

The interview…

We start off by talking about some of the challenges of being a CIO in the (largely online) gaming sector, one of which is that there are major (often sporting) events that happen at certain points in the year, and they have to be ready for those spikes in capacity demand.

Another major challenge in the sector is security, about which Fin asserts “we’re hyper-concerned about security in our world because we’re even more highly regulated than banking”. This is largely due to concerns about data loss, particularly in relation to the Cloud. When talking about this, he makes an excellent analogy: “if I put my bike in your house and it’s stolen, who’s responsible for that loss? It’s usually me”. This is a primary concern, and one about which Fin and his team have to be super diligent.

Sticking with Cloud technology, and the status of it within his sector, Fin feels that they are on a similar journey to many companies and industries, and that journey entails moving from “credit card Cloud” to “back office Cloud”. To elaborate, moving from niche Cloud use cases to IT teams working in a digital world, where they have back office systems (eg. HR, finance, ticketing) that are becoming “cloudified”, freeing the team up to spend more time on frontend work.

“But for us, like a number of companies, the next level will be enterprise level cloud, which is really a hybrid. It’s a capacity-on-demand model – recovery-as-a-service – or as Joe Baguley of VMware would call it, data center N+1, so that you’ve actually got this reliability in your production system.”

Ford deploys connected car platform on Microsoft’s cloud

Source: Business Cloud News

Ford-connected-car-platform-300x204Ford plans to roll out the Azure-based service later this year

Ford Motor Company and Microsoft have teamed up to create the Ford Service Delivery Network, a cloud-based connected car platform for Ford vehicles the companies said would make it easier and faster to add more in-car digital services.

Microsoft said the service will provide Ford a global platform to enable over-the-air software updates and expand availability of MyFord and MyLincoln Mobile connected services, which ships with features like scheduled remote start, vehicle finder, and vehicle status (fuel or charge level, tire pressure).

The connected car platform will be hosted on Azure-based technology in a combination of Azure and Ford datacentres.

“As consumers shift toward more cloud-based services, the Ford Service Delivery Network architecture is a strategic approach to keep vehicles up-to-date and relevant throughout the vehicle ownership period by making it easy to add or evolve services. Microsoft Azure provides a global common cloud platform that allows Ford to deliver services worldwide and scale quickly to reach its broad customer base,” explained Sanjay Ravi, senior director of worldwide manufacturing at Microsoft.

“This means that Ford can send updates as they become available, ensuring customers will have the latest technology as it becomes available,” Ravi said.

Customer deployment will begin later this year, the companies said.

Microsoft is among a growing fleet of technology firms looking to capitalise on growth of the connected car market. According to global telecoms association the GSMA, the size of the market will nearly triple over the next four years to $53bn.

Coke is IT: Using Cloud for Mission-Critical App Consolidation #CloudWF

Cloud-World-Forum logo with 2015 dates

The Cloud World Forum is truly shaping up to be the ‘must-attend’ event in the calendar with registrations 60% up on last year.

If you haven’t already, click here for your FREE pass!

We’re delighted to confirm Jane Gilmour, International CTO of Coca-Cola will be speaking at the Cloud World Forum on ‘IoT and the Coca-Cola Smart Vending Machines‘! In anticipation, we thought we’d share a great article from our 2014 Coca-Cola speaker, Onyeka Nchege, CIO of Coca Cola Bottling Company Consolidated on ‘Using Cloud for Mission-Critical App Consolidation.’

Coke is IT: Using Cloud for Mission-Critical App Consolidation

onyeka-300x200

In recent years, North America’s largest Coca Cola bottling company has increased the number of cloud services it uses. And along with three other large US-based bottlers most recently began an ambitious project to migrate its on premise ERP application‑its crown jewels‑to the cloud. But Onyeka Nchege, chief information officer of Coca Cola Bottling Company Consolidated explained to Business Cloud News that despite working as separately owned organisations, Coca Cola is a collaborative effort, making the individual companies ideal candidates to leverage the economies of scale cloud services deliver.

CCBCC has shifted its focus in recent years to cloud services primarily because of the perceived benefits associated with flexibility and time-to-market.

The firm now uses ServiceNow for IT service management, which has helped the company streamline its internal helpdesk processes, and it’s also using a range of cloud-based services for human resources. The company is using Cornerstone OnDemand for talent management and Coupa for expenses management, all fairly light-weight software as a service applications.

Nchege says that the company, which was founded in North Carolina in 1902, is like most large, well-established firms with a large estate of legacy IT infrastructure: it had to do a lot of things in order to prepare for its move to the cloud.

We had to wrap our heads around this culturally. We shied away from moving to the cloud for so long and the business being as old as it is, a big part of moving bits and pieces out to the cloud first was to get our organisation comfortable with this new paradigm,” he says.

The biggest risks of moving to the cloud have less to do with technology and more to do with lack of education. It’s about trying to understand what you don’t really know, which is why we started with non-business critical applications.
