The Advantages and Disadvantages of Multi Cloud Computing

Every Little Thing You Need to Know About Cloud Computing

Multi cloud computing, where multiple cloud services are put to use to create a single overarching infrastructure, is becoming increasingly popular amongst larger enterprises. Many companies already use more than one cloud provider and over 30% of them use upwards of four. By the end of the decade, it is believed nearly all enterprises will have adopted a multi cloud strategy of some kind, as it gives them greater flexibility and even more potential for rapid innovation and deployment.

However, with other possible options available, such as developing a hybrid cloud infrastructure, it is important that those who make the decisions are fully aware of the advantages and disadvantages of adopting a multi cloud strategy and in this post, we seek to highlight what these are.

The advantages of multi cloud

6 Ways Kubernetes Simplifies Multi-Cloud Management

By far the main benefit of creating a multi-cloud infrastructure is that it provides enterprises with the flexibility needed to innovate at speed. The reason for this is that it doesn’t tie them to the specific set of services provided by individual cloud providers. As a result, the way an enterprise chooses to innovate its own applications and services is not restricted by the limitations of a single host.

If a company relies on a single host, it may find it is adequate for the vast majority of its needs. However, if using that host means the company needs to make compromises on development then its innovations may end up being curtailed. Rather than go through the trauma of migrating all its services to another host that can help it innovate in the way it wants to, multi cloud enables it to run different services with different providers, each one offering the most advantageous platform for its specific workload. In this way, a multi cloud infrastructure is the best solution for developers looking for platforms that meet the specific needs of individual applications or services.

One example of this could be with GDPR compliance. An enterprise that uses cloud services based outside of the EU might find it easier to comply with GDPR if it used an EU based provider for the storage and processing of data pertaining to EU citizens.  Another example is with performance. Using a cloud provider with a datacentre in a particular geographical location could improve performance within that region simply because of its proximity to users.

Another advantage of multi cloud is its ability to cut storage costs. Despite the price of data storage coming down, the ever-increasing volumes of data being collected means enterprises are still spending significant amounts on storage. However, the competition between providers that forces prices down means that those with multi cloud infrastructures can easily shift their data to the cheapest provider whenever prices change.

The final benefit of a multi cloud strategy is that it reduces the potential for vendor lock-in. The main risk here is that an enterprise can become dependent on the technology employed by a particular provider. However, by making the appropriate choices when developing an infrastructure and finding another provider where a compatible, redundant platform can be created, this can be overcome.

The disadvantages of multi cloud

The Use of Multi-Cloud: Pros and Cons

The obvious disadvantage of using a multi cloud infrastructure is that the wider the range of cloud services an enterprise uses, the more complex it gets to manage. Failure to manage the system adequately can increase the costs of using such a system and could affect business agility.

One critical area which needs to be managed effectively is security and a multi cloud strategy can make this more challenging. By using a variety of public cloud services, the line of defence runs across more than one single provider, so it is essential that robustly secure networking and security measures are put in place. Areas which need close scrutiny include finding ways to monitor across different cloud platforms and ensuring that governance is comprehensive and robust.

A final issue with multi cloud is how to manage redundancy and high availability effectively and efficiently when using more than one provider. In instances where this is not efficiently managed, there can be the potential for financial wastage.


While multi cloud infrastructures are more complex and provide a bigger challenge for management, they do offer significant benefits. In a market where everyone is utilising technology to outpace their competitors, the need to innovate and deploy quickly can be the difference between survival and going under. A multi cloud infrastructure enables enterprises to remain a force to be reckoned with, providing the essential flexibility that is so crucial for rapid innovation.

Why User Authentication is Essential for Cloud-Based Systems

Cloud-enabled workforce models to disrupt and shape future Asia Pacific workplaces: Colliers Research - The Economic TimesAs businesses move more of their services on to web-accessible, cloud-based platforms, the need for robust security grows increasingly important. One key element of this security is controlling who has access to your data and applications. To strengthen security, reduce risk and improve compliance, it is essential that only authorised users get access to a company’s system and that authentication is required before that access is granted.

Cloud authentication explained

Cloud authentication is the means of verifying that someone logging in to a cloud-based platform is the person they claim to be. It is a way of preventing stolen usernames and passwords being used to log in to the system. The user’s identity is authenticated by cross-referencing information stored on a database with information held by the user, such as PIN numbers, biometric data or the use of secret questions. If the information provided by the user is identical to that stored in the database, authentication takes place and access is granted.

Authentication isn’t just required for people. Companies may also require external machine access to carry out automated services, such as cron-jobs, remote backups, auto updates and remote system monitoring. In these instances, too, it is crucial that external apps are authorised so that hacking bots disguised as genuine apps don’t slip through the security net. Authentication in these areas can be done through the use of digital certificates and APIs.

Authentication and authorisation

Authentication Vs. Authorization | Difference between Authentication and Authorization - javatpoint

Authorisation is the granting of permissions for individuals to access different parts of a system. It is not desirable, in any organization, for every user to have the same permissions. Access to sensitive data, for example, might be restricted to only certain staff.

One of the advantages of authentication is that it helps prevent unauthorised users from accessing data they do not have the authority to see. In particular, it will stop employees who have forgotten their own passwords being able to log in using their colleagues account details and gaining access to all the areas they have permission to use.

Why authentication is so important

What Is a User Authentication Policy? - Cisco

Preventing unauthorised access to cloud-based systems is vital. Hacked companies face enormous consequences: operational downtime, significant fines, potential lawsuits, reputational damage, industrial espionage and ransom. Customers can suffer just as much as companies too, with financial information being sold on the darknet and sensitive data being leaked across the internet. Lose personal data under GDPR and you could face a fine of up to €20 million or 4% of global annual turnover.

Authentication is a process which protects web-based systems from hackers and without it, your entire system is vulnerable. Cybercriminals use seriously advanced software that can crack usernames and passwords and they also use other techniques to phish for credentials from employees. Authentication provides an extra layer of security, using information that hackers can’t use. In this way, they are prevented from getting access.

Practical authentication

One challenge for businesses that use cloud-based systems is how to balance ease of use with strict security. Strong security is essential, but it can also be a hassle for users who need a quick and convenient way to log on. There is a range of different methods which can be used, here are two of the most common.

Two factor and multifactor authentication

Is two-factor authentication (2FA) as secure as it seems? - Malwarebytes Labs | Malwarebytes Labs

To increase security, many organisations require two-factor authentication. This consists of a password plus one additional piece of information. Multifactor authentication requires a password and up to four other methods of verification.

There are four ways that a users ID can be authenticated, these are:

1. Asking for something the user knows, such as a PIN, date of birth or the answer to a secret question.

2. Using something the user has in their possession: customers may be required to get a code from a card reader or be sent a code to their smartphone.

3. Biometric data: the user may have to provide biometric data such as a fingerprint, photograph or retina scan.

4. Location data: smartphone GPS data and computer Mac addresses can also be used to verify the location of the user.

The need for strong authentication

Why You Need Advanced Authentication to Protect User Identities

The term ‘strong authentication’ is used to describe systems where authentication is robust enough to guarantee its security. What ‘robust enough’ means, however, depends upon the needs of the system, how critical its apps are, how sensitive the data it holds and the type of organisation it belongs to.

Some organisations may be adequately protected by two-factor authentication, however, for those with high-security requirements, multifactor authentication is the standard practice.

Many companies are now using smart card technology for authentication. Here, biometric data, passwords and other vital information is stored on a smart card and the card is used by inserting it into a reader and inputting a PIN. Contact less cards can also be used by tapping against an RFID reader. Lots of organizations use the same card to grant physical access to the companys premises.


Authentication is essential for organisations wanting to keep their systems and data secure, especially when it based in the cloud and can be accessed over the internet. To ensure your system is well protected, you should, as a minimum, use two-factor authentication. However, if you hold sensitive personal data or run critical applications online, then multifactor authentication may be the safest option.

Predictions for the Cloud service in 2019

Predictions for the cloud in 2020 - Information Age

2018 saw important technological advances in cloud computing that made businesses take a fresh look at how it could help them achieve their goals. In 2019, we are likely to see a further shift towards the collection and use of data, including that gathered from business processes and external data sets.

To enable businesses to make the most of this, we’ll see organisations move from standard infrastructure as a service (IaaS) solutions to cloud services with more advanced features, such as AI, machine learning, blockchain and analytics. Hand in hand with this, we are also going to see more organisations adopt hybrid and multi-cloud environments which provide them with a more effective infrastructure and a better set of tools to achieve their aims. As a result, here at Anteelo, we believe the cloud trends mentioned below will become increasingly widespread as more businesses continue to develop their use of cloud technology.

A shift to hybrid and multi-cloud infrastructures

Why You Need To Shift To A Hybrid Cloud Infrastructure?

While many businesses have adopted cloud technology in some form or other, performance concerns and compliance requirement mean the majority of companies still run mission-critical applications and handle sensitive data in-house. In order to continue their move towards a cloud environment, companies will look at using a wider range of cloud options.

Public cloud will still be used as a cost-effective way to handle many processes, however, rather than rely on a single provider, many organisations will opt for a multi-cloud approach using a variety of hosting solutions for different purposes. At the same time, some workloads are more suited to private cloud networks and this means we’ll see an increase in the use of hybrid cloud infrastructures being developed.

While this mix of in-house, private cloud and public cloud architecture is obviously more complex, their integration will give enterprises the opportunity to build the most effective infrastructure it needs to drive the business forward.

A move towards open cloud technology

The shift to hybrid, multi-cloud environments naturally leads to the adoption of open cloud technologies. Doing so helps companies avoid vendor lock-in and gives them greater freedom to choose the right solution providers. Indeed, using open cloud technology improves the interoperability of platforms, apps and data which is ideal for businesses looking to create diversely hosted infrastructures.

Increased adoption of containers

Another consequence of companies moving towards a multi-cloud strategy is that they will want to deploy their apps across their multiple cloud platforms. This will lead to the increasing adoption of containers which will enable migration between various IT environments to take place easily and quickly. Key to this will be the use of the open source tool, Kubernetes, which enables the deployment and management of container-based applications.

An emphasis on security

Any move to a hybrid cloud setup means enterprises will need a more sophisticated approach to security. Using the services of multiple cloud providers means they will need to consistently manage all the threats to their applications and data across all vendors. An important aspect of this will be the need to get developers to integrate security features into their apps during development in order to ensure better app visibility, protection and control.

Skilling up

Adopting a hybrid, multi-cloud approach means IT teams will need to develop new skills and practices in the way they operate. While relying on managed services may still be appropriate in some situations, there will be an increased need for staff with skills in using cross-platform tools, automation and data integration.  The training up or recruitment of specialists, such as cloud architects, service brokers and automation engineers may be a necessity.

Rapid growth in edge computing

The huge rise in the numbers of connected devices and the emergence of 5G networks means that 2019 will see edge computing grow rapidly. Its use will enable companies to significantly benefit from the analysis of all the valuable data being harvested from sensors and other IoT devices in operation. Whether to gain customer insights, improve operation efficiency or for real-time condition monitoring, the use of interoperable technologies enables edge locations to remain synced with the company’s system to ensure it has a consistent overview of the wider network.


As you can see, the big development in 2019 is the move towards a hybrid, multi-cloud strategy where enterprises create bespoke IT solutions that combine public and private cloud service with in-house IT. Hand in hand with this will be a move to open source cloud technology, the increased adoption of containers, a stronger emphasis on security, the skilling up of IT teams and a rapid growth in the use of edge computing.

Cloud-automated IT eliminates shorcomings of Traditional IT model

Cloud Computing Risks, Challenges & Problems Businesses Are Facing

For small and medium-sized companies, the traditional IT model of an on-premises network built and operated with an in-house IT staff is often fraught with problems.  IT teams are stretched to capacity simply keeping the lights on and there are always going to be issues with systems performance, network reliability, end user productivity, data recovery, security and the help desk.  Staffing is another constant challenge. And if companies decide to outsource some IT functions, they end up with multiple service providers, which creates additional headaches.

The problem is highlighted in the 2018 State of the CIO survey conducted by CIO Magazine, in which CIOs said their role is becoming more digital and innovation focused, but they don’t have time to address those pressing needs because they are bogged down with functional duties.

The common business challenges reported in the survey are often symptoms of needs that are misaligned with technologies and service providers, plus the lack of budget to address the problems.  Those challenges typically revolve around:

  • security and disaster recovery
  • lost productivity due to downtime and end users waiting for support
  • shadow IT and users not following security training
  • escalating or unpredictable costs
  • outdated infrastructure
  • shortage of talent
  • multiple tech providers and systems working at cross-purposes

Smaller businesses that may have turned to traditional managed service providers quickly discover these services lack seamlessness and result in reactive support challenges. According to the Ponemon Institute’s State of Endpoint Security Risk Report, 80% of these reactive issues can be eliminated through standardization and automation.

Moving to a cloud-based IT infrastructure

How Can Migrating to the Cloud Help Customers?

Debunking the multi-cloud myths - Information Age

There are many benefits of migrating to the cloud: financial savings, increased agility, tighter security and uninterrupted service, just to name a few. But one often overlooked benefit is the improvements it brings to the customer experience and the positive effects this has on user trust and satisfaction, brand engagement and a company’s online reputation.

Improving the user experience is increasingly important for an enterprise’s success. According to Bloomfire, over 80% of businesses see the user experience as something which helps differentiate between competitors and, by the end of the decade, it is projected to overtake price and product choices as the main reason why consumers choose one brand over another.

Online, where consumers expect immediate, unlimited and uninterrupted access to information, products or services, businesses that still use non-cloud systems may miss out on the opportunities that the cloud has to offer. Migrating to the cloud provides the tools and services businesses need to participate in today’s competitive, on-demand marketplace, enabling them to enhance the customer experience and reap the rewards of doing so. Here are the ways migrating to the cloud can improve your customers’ experience.

Give customers 24/7 access to your products and services

Still Not Providing with 24/7 Customer Service? Here Are 9 Reasons Why You Should Start Right Away! | CommBox

The days where customers were prepared to wait for usual business hours to get in touch with a company are over. Today, they expect online operations to be available 24/7, whether that is to buy products, contact customer support or access online services. They also expect that these things can be done from anywhere, using any type of connected device.

By migrating to the cloud, it means that businesses have a much greater flexibility to put these things in place. For example, as employees can connect with work-based applications anywhere they have a connection, it means they can deal with customer service enquiries even when they are out of the office, helping expand operations and keeping costs to a minimum. Indeed, by using AI chat boxes, many of the inquiries a company has out of hours can be automated with only a minimal need for any human interaction.

This 24/7 availability can be provided for many services, such as product sales, ticket ordering, delivery tracking and much more.

Provide a one-stop shop

Qt 6.0 to provide one-stop-shop for software design and development

Ever had the experience of waiting for ages in a phone queue and then, when you finally get through, to be told you need to call a different number? There is nothing more frustrating for a customer than finding out they cannot access all a company’s services from a single point of entry, whether this is on the telephone or online.

Thankfully, the tools and systems available to companies which migrate to the cloud enable them to provide the integrated services that their customers demand, without them needing to leave the website.

The applications available in the cloud provide customers with easy to use interfaces from which they can manage all their services from a single place, whether on a website or smartphone app. Just think of all the things that online banking customers can now carry out on a bank’s website or apps. And if they have a problem, they can have access to support using the same interface no matter where they are, what time of day or what device they are using.

Offer personalised experiences

The Importance of Digital Personalization in B2B Marketing

Despite all the concerns around data privacy, most customers prefer it when companies provide them with personalised shopping experiences. It’s great for consumers seeing products and services that are tailored to their needs and desires and putting these things directly in front of customers certainly helps improve sales. It’s a win-win situation for both consumer and company and something we are seeing a lot more of when we visit websites.

The reason companies can provide personalised shopping experiences is because of the vast amount of data that is made available. Websites can track browsing and shopping history; they provide wish lists to see what people like; if customers don’t inform them directly, their algorithms can quickly ascertain a consumer’s age, gender, family background, geographic location and similar data; and all these things can be compared with the data of those in a similar demographic. The result is that users of these websites see an increasingly accurate guess at the things they are looking to buy and this increases their chance of buying them – especially when the company uses this data to incentivise a purchase through offers and discounts.

To provide personalised shopping experiences, however, all that data needs to be collected, processed and analysed. And there is a lot of data to collect. Cloud computing offers the best way to do this, providing unlimited storage and processing capacity, charged for on a pay as you use basis while allowing the use of widely available big data and AI applications to undertake the data crunching.

Improve the trustworthiness of your brand

6 Ways to Establish a Trustworthy Brand | ZoomInfo Blog

The cloud provides several ways to improve the reputation of your brand. With high availability cloud hosting, the bad press associated with application downtime can be a thing of the past; the security features available from service providers means that there is a reduced risk of IT systems becoming victims of cyber attacks, infections or ransomware; and the choice of cloud-based tools on offer provides a range of ways to ensure that customers’ needs are dealt with quickly. Together, these things ensure that customers see your online provision as something that is both reliable and trustworthy.


Migrating to the cloud can greatly improve the user experience, helping to attract new customers and retain existing ones. With many tools available, the cloud can help businesses give their customers the online experiences they demand, providing 24/7 access to integrated services and personalised shopping from a reliable and trustworthy business. With these in place, businesses will have a clear advantage over their competitors.
