hybrid cloud computing

How Your Business Could Benefit from a Hybrid Cloud Approach

In the not-too-distant past, many firms proudly promoted their “cloud first” strategies. By moving infrastructure and applications to the cloud, these adventurous organisations hoped to increase operational flexibility (and reduce costs). Over time it has become apparent that some workloads are not currently suited to hosted platforms. Anything that is time sensitive (IoT and real time analytics) or exceptionally sensitive (personally identifiable information, intellectual property) may be more effective in the on-premise data centre. The hybrid cloud developed as a natural response to these different workloads – and has gone on to become the new norm for most organisations. This change in strategy is not necessarily a bad thing – there are definite benefits to the hybrid operating model according to research from the Aberdeen Group.

Improved application performance

Speed of IT is closely associated with speed of business, so any gain is important. 50% of hybrid cloud adopters report improved application performance.

Increased IT infrastructure agility

The ability to change operations and processes quickly is vital to competing with disruptive start-ups and shifting customer preferences. 43% of hybrid cloud users believe they have a data platform capable of supporting that change.

Genuine cost savings

Early cloud platforms promised enormous financial savings – but only if applications were re-engineered around the pay-as-you-use business model. By retaining control of some apps and data in house, 38% of hybrid cloud using companies have achieved an overall reduction of IT expenses.

Improved system reliability

In most cases, data availability is as important as speed. By moving to enterprise-class hybrid cloud platforms operated by data centre experts, adopters can reduce at least some of their on-premise footprint. The fewer “moving parts” they operate, the lower the risk of outage – as confirmed by 35% of users.

Building for the future

Once they have established some of their operations in the cloud, hybrid users have the option of increasing capacity and resources as and when required. And as other applications become cloud-enabled, they can migrate more of their workload off-site to compound the benefits and gains listed here.

Hybrid cloud doesn’t “just happen” though. You will need a proper cloud strategy, one that assesses current workload and identifies which assets are suitable for hosting in the cloud. Systems that remain on site will need at least some degree of reconfiguration for optimal performance and compatibility.

With the right technology platform and cloud partner, you can define a roadmap that offers maximum flexibility moving forwards. In return you can expect to reduce operating risk and increased control of your entire IT estate.

Oracle Linux provides OS optimisation for Oracle Database

Oracle Linux – The Only OS Choice for Oracle Database

As we’ve discussed previously in our blog, running Oracle database applications on Oracle SPARC provides significant performance and stability benefits. But for organisations that rely on x86 servers performance gains need to be realised elsewhere, namely the operating system. Solaris is obviously one option, but Oracle also offer their own Oracle Linux distributions. Available in two kernel variants, Oracle Linux is specifically engineered for open cloud infrastructure in your on-premise data centre. And it has the advantage of being completely free to download, install and use.

Overcoming common OS problems with Oracle Linux

The Unbreakable Enterprise Kernel (UEK) variant is enterprise-focused, offering superior stability, scalability and performance with an emphasis on Oracle Database. However, UEK offers several other key benefits that make it a worthy alternative to Solaris.

Reducing downtime

Oracle Linux is a rock-solid, proven operating system suited to enterprise-class workloads. But thanks to the unique Ksplice Zero Downtime Updates technology, core OS components can be updated on live systems without rebooting. Ksplice ensures optimisations and security updates are applied quickly and effectively without affecting availability.

Optimised for Oracle

There are numerous workload optimisations available for Oracle Linux. Among the headline benefits is a potential 3.6x performance gain of SPECjbb by eliminating lock contention. The OS also automatically locates processes near its RAM for faster retrieval and execution, particularly for workloads that do not fit on a single NUMA node.

Enhanced security

The Ksplice engine ensures that kernel, hypervisor and user space libraries are kept patched and updated against security vulnerabilities. It will also audit your system to identify privilege escalation vulnerabilities that need to be addressed to prevent system compromise. In recognition of these capabilities, Oracle Linux has received Common Criteria (CC) certification and FIPS 140-2 validation for its cryptographic modules. Oracle Linux also features hardware accelerated memory encryption to prevent data loss or theft and to improve the overall security protections of the host system.

Scalable file systems

One of the few certainties in server architecture is that storage demands will continue to grow exponentially. Scalability of underlying file system will be vital to meeting future resource demands. The native XFS file system is not only fully scalable, but also offers ‘near native’ I/O performance. For mission critical real-time database operations, reducing latency is an operational priority.

Containerisation

Containerisation is an essential aspect of cloud-based operations, even in the local data centre. Oracle Linux supports both Docker and Kubernetes to maximise the potential of your hardware investments.

Completing the Oracle technology stack

Oracle Linux provides an important interface between database and bare metal. The UEK kernel can be used on a range of server architectures, including x86, SPARC and ARM to ensure peak performance and compatibility throughout the entire technology stack. Choosing any other OS will create a ‘gap’ in the stack, ensuring that your database never reaches its full potential.

White Paper: Why Oracle Database Runs Best on Oracle Linux

Why Oracle SPARC for your Data Centre

Why Oracle SPARC still has a place in your data centre

Despite the general trend towards cloud computing, there will almost always be a need for onsite data storage and processing. Given that hardware ages at the same time as stakeholders become increasingly demanding, you will inevitably need to refresh your data centre hardware periodically.

So why should you choose Oralce SPARC systems instead of cheaper, generic servers?

A perfectly optimised technology stack

Oracle SPARC servers are admittedly not suitable (or necessary) for every IT environment. But when it comes to running Oracle databases, it would be a serious investment mistake not to choose SPARC.

Every SPARC system has been designed and optimised for Oracle workloads. The M7 processor has been tuned to handle transactional workloads and data analytic workloads simultaneously – in real-time – for maximum performance. In addition to superior speed, SPARC systems offer seamless security that protects the entire stack, from bare metal through OS and applications.

Meeting the challenge of legacy applications

For well-established businesses, legacy applications are essential to operations – otherwise, they would have been replaced. These applications pre-date the cloud and may rely on now-redundant technologies. To stay in operation may normally require a rebuilding infrastructure from scratch at a significant cost.

Oracle SPARC servers provide a platform capable of supporting legacy applications and delivers a much-needed performance/security boost. The performance gains are complemented by lower cost of deployment and an increase in overall security thanks to the close integration of hardware and software.

Easing your transition to the cloud

Even as you refresh your data centre, you will also be planning the future of your data operations. As mentioned earlier, the cloud will almost certainly factor in your strategy, so it makes sense to consider how to smooth the transition when you are ready to begin the migration.

The Oracle SPARC Cloud Service is built using the same technology as SPARC servers deployed in on-premise data centres. Which means that any systems you build now will be fully compatible with Oracle Cloud. Future migration projects will be both quicker and cheaper because code will not require significant re-engineering to take advantage of the hosted platform.

In fact, SPARC users can simply extend their environment into Oracle Cloud using the dedicated compute service that has been built for precisely this purpose.

Investing in on-premise SPARC servers is an investment in the future

With the prevalence of “cloud-first” strategies, it seems that the era of the on-premise data centre is in decline. But as demand for exceptional computing speed and real-time processing accelerates, your choice of local servers becomes even more important.

Thanks to the full-stack optimisation of SPARC servers and the seamless workload cloud transitioning functionality, investment in an Oracle environment will deliver more benefits for longer. If nothing else, your business buys time to solidify its future cloud strategy and enjoys superior performance and security in the interim.

To learn more about your SPARC server options SPARC and the advantages available to your business. If you are looking to define a long-term strategy for your SPARC enviroment our  latest infographic  looks at some of the opitons and questions you should be asking.

Oracle PCA

Oracle PCA – Beyond the Limitations of Hyper-converged Infrastructure

Regardless of industry, data is the lifeblood of strategic operations. The ability to access actionable insights from corporate information stores will be crucial to becoming a truly agile organisation that can face the challenges of the future.

To ensure that the on-premise data centre is both scalable and performant, CTOs have been choosing converged infrastructure. By unifying and commoditising hardware, they can accelerate installation as demand for capacity increases.

But for line of business applications where every millisecond matters, Converged Infrastructure (CI) and Hyper-converged Infrastructure (HCI) may not be the optimal choices.

The limitations of converged infrastructure

Converged Infrastructure changed the game for many CTOs by dramatically simplifying the process of specifying data centre hardware. Uniting various best-of-breed technologies under a common management interface, they know that each CI unit will “just work”.

However, CI is purely a platform on which to build virtual servers. Your teams will still need to install and configure operating systems, databases and software. And they will then be expected to support the various components that make up the CI stack.

Even if your business has the necessary skills and resources to manage the entire stack, the total cost of ownership of CI systems will be higher than expected.

The limitations of hyper-converged infrastructure

Still using components (networking, storage, processing etc) from different OEMs, Hyper-converged Infrastructure (HCI) systems have been designed from the outset for maximum interoperability and superior central management. As a result, HCI management is typically easier and cheaper, although the hardware costs a premium.

Despite this even tighter integration, the same fundamental problem is still present. As the name states, HCI begins and ends at the infrastructure layer. Your team still needs to complete the installation and configuration of the software and systems on which the business relies.

Physically adding capacity is easy – but preparing each unit for deployment is costly. As is the cost of ongoing management and administration. And without in-depth knowledge of the hyper-converged infrastructure components, can you be sure that the environment is fully optimised for your workloads?

The Oracle PCA difference

The Oracle Private Cloud Appliance (PCA), takes a different approach by integrating the entire technology stack into every unit. This ensures total integration between hardware and software for optimal performance.

PCA is also quicker and cheaper to deploy because there is no additional software installation or integration required. Dropping in new units to increase capacity is as simple as it sounds.

Oracle Private Cloud Appliance makes perfect sense for Oracle customers. The private cloud model has been pre-configured to deliver optimal Oracle Database performance out-of-the-box; immediately you benefit from improved data I/O. PCA is faster to deploy and more performant, so customers benefit from increased speed and efficiency at every point of the HCI lifecycle.

End to end control of the technology stack reduces your point of contact for vendor support to one – Oracle. Similarly, software patches and security updates cover the whole stack to ensure zero-downtime for maximum availability and minimum manual intervention.

Control the whole stack for optimal performance

HCI has simplified data centre expansion – in theory. In order to realise maximum benefits however, you need a solution that takes integration further than just the infrastructure layer, one that unifies the entire stack from bare metal to applications.

For Oracle customers the solution is clear. Oracle PCA fulfils the promise of HCI with the added benefit of complete control of the technology stack. Users can rapidly deploy cloud-like processing and storage functionality and benefit from reduced maintenance and support costs.

The performance advantages of an integrated technology optimised for their line-of-business applications and databases are already significant. But because Oracle PCA can be deployed and made operational more quickly, owners will simultaneously realise a greater return on investment and a reduced total cost of ownership.

5 Stars Representing 5 Reasons to Chose Oracle Cloud

5 (More) Reasons to Choose Oracle Cloud

Despite not being the most popular hosted platform, Oracle Cloud offers some significant benefits to users. The first article in this series outlined five reasons why you should seriously consider making Oracle your platform of choice – and why your competitors are missing out by ignoring it.

But as you might expect, there are more than just five reasons to choose Oracle Cloud. So, here are five more to consider:

1. Cost-optimised platform

Hosted infrastructure (IaaS), platform (PaaS) and software (SaaS) are billed on a pay-as-you-use basis. So, the more storage or CPU cycles you use, the higher your monthly bill.

Thanks to the infinite scalability of the cloud, you dynamically add resources as they are required, and scale back as demand falls. However, the Oracle cloud typically requires fewer compute servers and block-storage volumes to perform the same tasks – so you achieve the maximum price: performance ratio and save money at the same time.

And thanks to a financially backed, end-to-end SLA, you will also receive compensation if performance is ever impaired.

2. AWS-beating performance

AWS is the most popular cloud platform – but that doesn’t make it the best. Having been designed from scratch to support Oracle databases, the Oracle Cloud is not only 66% faster, but also up to 65% cheaper.

And remember – AWS does not offer native support for Oracle RAC, Oracle Autonomous Data Warehouse or Autonomous Transaction Processing. Less than ideal if your business operations are reliant on Oracle databases.

3. Enterprise power for SMBs

Oracle’s product line is synonymous with enterprise computing, but the cloud is making the same enormous computing power available to SMBs. With scalability as standard, you can expand application development and adoption as the business grows without sacrificing performance or breaking the budget.

4. Microsoft expansion options

AWS tries to tie users into the Amazon ecosystem, making inter-operability time consuming and difficult. But your business almost certainly relies on a best-of-breed collection of systems from multiple vendors.

In recognition of this reality, Oracle and Microsoft have developed a cloud interoperability partnership. This allows customers to use both Oracle and Azure cloud platforms to build a new hosted best-of-breed platform that leverages the unique benefits of each. And cross-cloud interconnect ensures you can move your data wherever you need it without creating a serious technical headache.

5. Your apps, your way

Building a platform for the future requires maximum flexibility and control. By offering a fully integrated application development platform you can build the applications your business needs.

Oracle AppDev has been designed to support your DevOps strategy and to accelerate development and delivery. And with support for containers and cloud-native applications, you can unleash the full power of the cloud for your systems.

Building for the future

The Oracle Cloud may have a smaller user base, but this creates an opportunity for Oracle database users. Faster and cheaper than AWS, with greater flexibility and inter-operability, if you choose Oracle Cloud allows you to build a platform that accelerates the speed of your business -and to build the data-driven applications you really need.
