Cloud Harmonies: Securing and Safely Sharing Your Data

As Nobel Laureate Bob Dylan sang in his distinct drawl, “the instances they are a-changing’”. Way back when Bob picked up his pencil to write down his Nineteen Sixties traditional in long-hand, the cloud turned into both a visible mass of condensed watery vapour floating in the ecosystem or described a kingdom or reason of trouble, suspicion or gloom.

Fast ahead to today’s always-connected global and instances are still changing – and continuously. Now, there may be a deluge of data flowing into firms – from smartphones to clever water meters – and cloud computing is a phenomenon transforming organizations.

Whether you are a global agency or an enterprising entrepreneur, cloud computing brings world-class information centre capabilities for your fingertips. Gartner predicts that the worldwide public cloud services marketplace will grow 18% in 2017 to $246.8B up from $209.2B in 2016 and 451 Research expects growth in web hosting and cloud offerings spending to outpace increase in usual IT spending by 25.eight% to 12% this year.

But concerns approximately statistics safety and governance are greater than a dark cloud at the horizon. Although the cloud promises establishments the ability and elasticity to leverage information to allow smarter business decisions, groups need to trust that the data may be shared securely. Organisations will lose out on a key gain of cloud technology if their statistics isn't always nicely governed and that they can’t share information risk-free.

Daring to share a precious asset

Data is the crown jewels of an organisation. The manner statistics is stored, manipulated, analysed and controlled is crucial to being aggressive and compliant. With EU GDPR less than one year away and other destiny regulations worrying more information transparency on the horizon, enterprises want to be able to aggregate records from disparate sources to get a single, 360-degree view of customers or transactions to make certain compliance and maximise the business fee in their statistics.

Adopting a cloud model permits personnel, clients, partners and providers – as well as the cloud provider’s operations team – get admission to to an organisation’s network and offerings. Naturally, security is always of paramount problem, no longer to mention the want to preserve close song of who has get admission to to what information. Given those requirements, cloud protection has to be bendy sufficient to allow a few users to get admission to the data, however no longer necessarily others.

[easy-tweet tweet=”The data inside the public cloud environment needs to be secure. ” hashtags=”Data, Cloud”]

Public cloud providers are doing a wonderful task of traditional community and operational protection, however protection calls for a multi-layered method. Just as shielding the crown jewels calls for extra large protection than the hi-tech cameras and security guards keeping a watchful eye at the Tower of London walls, cloud safety additionally wishes to head past a ‘perimeter strategy’.

The statistics within the public cloud surroundings needs to be secure. While the cloud environment can be stable, the statistics inner that environment won't be, and this is the duty of the data proprietor or custodian – now not the cloud issuer.technology insurance
 For this motive, records-degree security internal a public cloud surroundings turns into as critical, if not greater so, than the network security. If an organisation’s database lacks comprehensive, hardened security, it's far a ways much more likely to suffer a successful records breach and make the headlines for all the incorrect reasons.

Before shifting any sensitive statistics to the cloud, enterprises need a database that gives a rigorous stage of statistics protection even as allowing all the elasticity and versatility required to take full advantage of the cloud. For example, an agency-hardened NoSQL database wraps layers of security proper round the information itself, using advanced encryption, role-based totally get admission to controls and different protection features to mitigate the chance from both insider threats and external hackers.

Data governance clouds the problem

Data governance casts a huge shadow on organizations, whether within the public cloud or on-premises. Even while organizations have devoted huge quantities of time gathering statistics and building records lakes, they can’t leverage their information belongings if the information isn’t governed properly.

Without governance, organizations might unwittingly disclose their facts crown jewels or violate information regulations. If sensitive statistics has now not been fully redacted – or hidden and transformed – it may result in a brush with the regulators for inadvertently exposing individually identifiable information (PII) approximately employees or customers. And, if facts lineage and provenance can’t be validated, companies can’t deliver statistics scientists, or testing teams access to the statistics for analysis because it represents too terrific a threat.

But there's a silver lining to the information governance cloud. Rather than seeing statistics governance as a weight on a agency’s shoulders, it is a manner to unlock the cost of information and drive enterprise cost. By untangling the knots of statistics currently isolated in severa silos in the course of their organisations, and applying effective metadata management abilties to their facts lakes via a NoSQL database platform, groups can make the most of getting their facts in better shape. And the use of bendy database technology with superior safety integrated, such as equipment to without difficulty and quickly redact facts, offers organizations the confidence to share their records accurately without worry/hesitation.

Cloud switching: keeping options open

The adage about ‘no longer maintaining all of your eggs in a single basket’ is one organization could do properly to take into account on the subject of cloud procurement. The march in the direction of hybrid cloud environments has momentum as CIOs accelerate using two public cloud services – generally Amazon Web Services (AWS) and Azure – to ensure they're now not locked into a unmarried supplier or location.

By mission all cloud application improvement the usage of a cloud-impartial database that works across each issuer, as well as on-premise, agencies could make the switch if their provider studies a breach or whilst an alternative vendor launches a brand new provider or speciality this is extra suitable to their business desires.

The outlook

By chasing away doubts about records protection and governance, groups can attention on the lowest line, and take advantage of all of the cloud has to offer regarding flexibility and agility. The cloud revolution will keep to transform business fashions and working practices. And with streams of his songs leaping 512 percentage globally after his 2016 Nobel Prize in Literature turned into announced, Bob Dylan could echo that nevertheless “the instances are a changing”.

OSS PaaS Rundown: Comparing Dokku, Flynn, and Deis Workflow

Open source software program is currently witnessing a renaissance. For every essential platform available, there is as a minimum one open supply alternative. Heroku made Platform-as-a-Service (PaaS) famous and is nevertheless one of the best PaaS providers available with hundreds of integrations to pick from. But Heroku can cost lots greater than you count on as your software grows in scale. Some popular OSS alternatives are compared below:


Dokku presents itself as “Docker powered mini-Heroku.” It is the smallest and only of all the options reviewed here. It comes with a web-based setup (after the preliminary installation) or can be installation in an unattended mode as well, that is suitable for deployment scripts and CI/CD. Heroku-like minded applications may be pushed to it through Git and it builds them using Heroku construct packs. The handiest downside is that Dokku is confined to a unmarried host. While it works for small programs like side-projects, the dearth of horizontal scalability makes it incorrect for larger applications. Dokku is likewise not capable of offer high availability because a unmarried server means a single factor of failure. This is in which Flynn comes in.

[easy-tweet tweet=”Large applications are moving towards microservices from monolithic designs” hashtags=”Applications, Data”]


Large programs are an increasing number of transferring toward microservices structure from monolithic designs. Services are divided as in line with their capability and are often a part of processing pipelines. There are even services for those services. For instance analytics from diverse resources can be clustered using an aggregator. Microservices provide the developer the capability to scale elements in their software independent of each different as per the load. Dokku is unsuitable for this sort of applications as they require a platform that can help multi-cluster deployments. 

Flynn changed into built with keeping excessive availability and scalability in mind. It may be run on a single server or can be scaled up to multiple nodes. Like Dokku, Flynn also works on the identical Heroku-like format. Applications are deployed the use of Git and constructed the use of build packs. Flynn’s additives additionally run interior a cluster as noticeably to be had Flynn apps. Flynn also consists of integrated databases that run on a cluster.visible technologies
 PostgreSQL, MongoDB, MySQL, or Redis may be initialized with a unmarried click, and it additionally affords console access to the CLI customers of those databases. Flynn offers a web-based totally dashboard for tracking and administering the cluster. It additionally suggests aggregated logs from all of the nodes there. HTTP, HTTPS, and TCP load balancing is integrated and automatically configured. Flynn also presents overlay networking for scaling applications and integrated service discovery, so that you do now not need to configure Consul provider yourself. Both Flynn and Dokku help Twelve-factor programs, making all Dokku programs well suited with Flynn. Flynn has help for outside plugins to extend it. It is constructed on an Ubuntu base. All in all, Flynn is a stable platform for growing scalable programs in a Heroku-like environment to your server. It can be visible as a successor of Dokku.

Deis Workflow

Deis Workflow is built on top of the battle-tested Kubernetes. It provides an smooth to apply the layer on top of a Kubernetes cluster to make application deployments easier. Deis Workflow is maximum popular a number of the three platforms discussed for huge and complicated packages. The platform is brought as a set of Kubernetes microservices. Both the platform services and the application runs in separate namespaces to split the workload. Deis Workflow can deploy new variations of the utility without any downtime using its services and replication controller. As with Dokku and Flynn, it additionally supports deployment through Git. It can be controlled via the CLI client or the use of the built-in REST API. It additionally includes an area router to put in force firewall policy within the cluster. All the code pushes, config adjustments and scaling activities are tracked and Deis Workflow makes it clean to rollback to any previous version with a easy API call. Additional workload which is not managed via Workflow may be introduced the usage of the underlying Kubernetes’s provider discovery. Using Deis Workflow requires initializing a Kubernetes cluster, which makes it a little much less newbie friendly – although Google Cloud Platform, Amazon AWS, and Azure Container Services all offer easy to use controlled Kubernetes set-ups. Once the cluster has been initialized, it can be installed with Deis Helm package manager. Deis Workflow also follows the precept of Twelve-thing programs. It can both use a construct % or create a brand new docker photo if a Dockerfile is found. Workflow is also built for scalability. It is built on a CoreOS base. For CAP, it makes use of Fleet and etcd for Gossip/RAFT from the underlying CoreOS. Logs and metrics can be tired to any supported sink. Deis Workflow additionally affords guide for in-constructed alerting based totally on predefined thresholds. Alerts may be despatched to a Slack channel, Pagerduty, to a custom webhook, or thru email.

Other outstanding mentions are PaaS like Cloud Foundry BOSH and OpenStack Solum. Choosing the only that fits your software excellent can be a strenuous task. The fine manner to do that might be to attempt out each of the platforms, beginning with the Dokku, that is the only. If the application requires extra flexibility and scalability, it might be higher to move on to Flynn at the price of some accelerated complexity. DevOps engineers who're already acquainted with Kubernetes will discover transitioning to Deis Workflow very smooth.

Moving to the Public Cloud is the New Norm for Businesses

Recent studies from Gartner predicts that the global public cloud services market will grow 18% in 2017, to a total of $246.8 billion. This is expected to hold to growth a ways beyond 2020.

Many organizations across the world have already adopted the general public cloud, on the premise that it gives a greater stable computing surroundings than many formerly had, and at a fraction of the cost. Indeed, public cloud has reached a tipping point: firms have now positioned their accept as true with in it in sufficient quantity for concerns around compliance and practical utility to now be mitigated, in turn, driving yet greater peer adoption.

Despite all this, there may be nonetheless some reticence. These range from security concerns and problems round data sovereignty to questions round control and third-party reliance, main some even to anticipate that a hybrid public-private technique is the excellent way forward. Just these days NSA whistle-blower Edward Snowden became the latest industry figure to take goal at the public cloud, accusing the era of being “disempowering”.

But nonetheless, the volume of adoption means that the question seems to have developed from “why use the general public cloud?” to “why no longer use the general public cloud?”. After all, on closer inspection, the arguments against public cloud do not always stack up.


Many enterprises cite security as one of the main reasons to eschew public clouds, in which applications and records are hosted on dedicated servers within a cloud company’s facts centre, accessible most effective via non-public connections.

[easy-tweet tweet=”We need to cast off the excuses not to rely on public cloud” hashtags=”PublicCloud, Hybrid”]

But that is outdated. Governmental departments are now the usage of Amazon Web Service (AWS) facts centres, meaning employer protection issues round public cloud adoption have in truth diminished. A prime example of trust within the public cloud comes from the Government Digital Service, which has said that it is a perfectly safe platform for data.

This is not to belittle the gravity of security considerations. Rather, public cloud provider providers, like AWS and Microsoft Azure, are absolutely privy to the dangers and are constantly making an investment in growing and enhancing their safety skills to stay one step beforehand of today’s continuously shifting protection panorama and shield customer information and applications. Even to the factor, ironically, that the funding and protection resilience outweighs that of maximum private datacentre set-ups.

Moreover, Gartner predicts that by 2018, better protection will in reality be the main motive why authorities businesses decide to apply the general public cloud.

Data sovereignty

Issues around information sovereignty are another capability impediment to public cloud adoption. The difficulty is that the statistics the corporation is storing could be situation to the rules of the us of a in which it's miles being stored.

However, in Britain the post-Brexit era will see an increase in British-primarily based records centres, with the authorities’s Public Services Network (PSN) weakening the statistics sovereignty argument in opposition to public cloud through demonstrating its confidence in the technology.information technology training
 This will also reduce latency and help to open the doors to new training of enterprises who're in want of actual operational savings, but were formerly locked out of using the general public cloud.


Another argument against the public cloud is that firms like to stay on top of things in their infrastructure and offerings, and do no longer need to be reliant on third-parties. A lack of schooling and early engagement steering on high-quality exercise is therefore referred to by businesses as a weakness of the general public cloud.

But authorities procurement tasks are beginning to break down large contracts. This affords the possibility to ease large legacy supplier lock-in, permitting small and medium suppliers to actively compete so one can supply on these challenges using the public cloud. Smaller gamers on smaller contracts mean that providers will start behaving more like structures integrators, working alongside customers to offer consultancy on first-rate exercise public cloud implementation.

A hybrid cloud instead?

While a hybrid cloud may appear to be the satisfactory of each worlds, it introduces greater issues than it solves. Private clouds, whilst inherently providing more manipulate, are greater luxurious to construct and hold than the public cloud, and do now not provide the same degrees of scalability and versatility.

A hybrid surroundings, to mitigate perceived weaknesses of the public cloud, sincerely does little more than introducing an additional level of complexity and control challenges, which is definitely unnecessary.

Hybrid cloud is really too complicated to manipulate without steady education and outside help, which brings us to the main cause that hybrid cloud is not a viable solution: value. In easy maths, adopting a hybrid cloud method adding the expenses of personal cloud, plus public cloud, plus tremendously skilled body of workers to manage the intricacy. And even after all this, the security of the personal – now not public – part of the cloud stays a subject. Furthermore, compatibility is a predominant issue whilst building a hybrid cloud and with twin tiers of infrastructure, a private cloud that the organization controls and a public one that the company doesn’t, the chances are that they will be running exceptional stacks.

We want to take away the excuses no longer to depend on the general public cloud. With governmental backing, high adoption, non-stop funding and low costs, the general public cloud is already the quality method for your enterprise. Besides, a number of the reasons holding returned the general public cloud are not honestly about the era itself, alternatively the negative mind-set round its adoption.
