SQL Server high availability and disaster recovery for AWS, Azure and GCP: A guide

The public cloud offers a myriad of options for providing high availability and disaster recovery protections for SQL Server database applications. Conversely, some of the options available in a private cloud are not available in the public cloud. Given the many choices and limitations, the challenge faced by system and database administrators is determining the best available options for each application running in hybrid and purely public clouds.

Organisations need to ‘acknowledge challenges’ in not keeping 100% uptime, argues Veeam

It’s the big downtime downturn; according to a new study from Veeam, three in four organisations admit they are not able to meet users’ demands for uninterrupted access to applications and data.

The findings appear in the company’s latest Cloud Data Management Report, which surveyed more than 1,500 senior business and IT leaders across 13 countries. Ultimately, the need for more sophisticated data management...

A guide to the key principles of chaos engineering

Chaos engineering can be defined as experiments over a distributed system at scale, which increases the confidence that the system will behave as desired and expected under undesired and unexpected conditions.

The concept was popularised initially by Netflix and its Chaos Monkey approach. As the company put it as far back as 2010: "The...

Avoiding cloud vendor lock-in: It’s all in the planning

The cloud computing world is becoming increasingly dominated by a small number of IT giants aiming to be your one-stop services shop. From infrastructure to software, one vendor could hypothetically provide an organisation’s entire IT system. Naturally, this is appealing to users that want to simplify their estate and partner with a well-established and reliable cloud host – but ask yourself, do you really want all your eggs in one basket?

With risks like hacking and large-scale...

How to leverage cloud architectures for high availability

Cloud architectures are used broadly nowadays; the cloud is a plethora of amazing alternatives in terms of services and solutions. However, with great power comes great responsibility, and the cloud presents itself as a place where failure can and eventually will occur. Thus, consequently, it will spread upon the entire architecture fast, possibly causing massive outages that can leave a business on its knees.

Okay, that’s not an overly optimistic scenario – more likely the opposite – but...

Back to black: How to ensure a data centre’s critical infrastructure works when needed

For cloud providers and their many customers a robust and continuously available power supply is amongst the most important reasons for placing IT equipment in a data centre. It’s puzzling therefore why so many data centres fail repeatedly in measuring up to such a mission critical requirement.  

Only last month, for example, cloud service providers and communications companies were hit by yet another protracted power outage affecting a data centre in London. It took time for engineers from the...

Companies moving to the cloud without assessing outage possibilities, research argues

Organisations are moving to the cloud without evaluating the impact of a cloud outage, according to the latest study from data management provider Veritas.

The report, titled The Truth in Cloud and put together alongside Vanson Bourne, found that an ‘alarming majority’ of firms shift full responsibility for data protection, compliance and uptime on cloud service providers.

Three in five (59%) of the 1,200 global business and IT decision makers polled said dealing with cloud service interruptions...

Cloud outages could cost US businesses $15 billion, says Lloyd’s of London

Here’s an interesting statistic to illustrate how much influence the major cloud providers have: according to Lloyd’s of London, US businesses could lose $15 billion if a leading vendor experienced downtime of at least three days.

According to the insurer, working in partnership with risk modelling firm AIR Worldwide in its ‘Cloud Down’ report, an ‘extreme cyber incident’ which took a top cloud provider offline for three to six days would also result in insured losses of...

As cloud infrastructure becomes more complex, security struggles with it

As more organisations get deeper into their cloud initiatives, their infrastructures become more complex – yet according to new research from WinMagic, security and compliance is struggling to keep up.

The study, conducted by Viga, polled more than 1,000 IT decision makers and found that while an overwhelming 98% of respondents say they use the cloud in some capacity – with on average half of a company’s infrastructure being cloud-based – security is lacking in comparison. Only one in...

Stronger cloud security and guaranteed uptimes? Yes we’ll pay more, say organisations

Three quarters of organisations would be willing to pay a premium to enhance their cloud services, according to the latest note from 451 Research.

In the latest from its Voice of the Enterprise series – this time around organisational dynamics in hosting and cloud managed services – the research firm found that companies were most likely to pay more for security guarantees than anything else.

Just under half (48.7%) of those polled said they would pay to enhance their security, ahead of guaranteed...

Five steps to gain data centre power chain management and risk assessment

It is a simple fact that data centre power outages will cause major business disruption in our connected and web delivered world. It’s very likely that a severe data centre power outage can cause a major loss of customers and damage the brand – as well as the stock price.

Everyone must face these facts, because there is no silver lining to a power loss incident. The potential ramifications might be irreversible and include that loss of trust, market share and reputation that are hard to quantify...

Some things should not go public: The risks of a single-cloud strategy

Both Amazon and Microsoft cloud users experienced majorly disrupted services earlier this year due to unforeseen outages on both the AWS and Azure platforms. Customers faced disrupted services with no access to vital apps or data and some companies were left without access to crucial SaaS-based technologies that inhibited business operations across the globe. This outage was met with the swift realisation that the public cloud may not always be the most appropriate solution for every workload. Keeping all...

Why companies are shifting to ‘IT as a service’ – and what you need to do about it

‘IT as a service’ (ITaaS) is on the rise as companies realise the benefits of contracting an IT service provider for all their business technology needs. While ITaaS is not a new concept, it has become a go-to operational model for medium-to-large sized companies that need 24/7 monitoring, managing, and sustaining of company technology.

Moving to ITaaS is an operational shift, where IT is run as a business and therefore can be optimised according to business needs. Companies that run hybrid IT environments,...

Four nines and failure rates: Will the cloud ever cut it for transactional banking?

Banks looking to take their cloud plans to the next level are likely to have returned to the drawing board following the latest Amazon Web Services outage, which disrupted the online activities of major organizations from Apple to the US Securities and Exchange Commission. One estimate suggests US financial services companies alone lost $160 million – in just four hours. It’s been a timely reminder that any downtime is too much in an always-on digital economy, certainly for financial services.
