How to secure your hybrid cloud?
The latest IDC study confirms that Cloud is one of the most popular storage solutions for businesses. In 2017, spending on cloud infrastructure rollouts jumped 20.9% to $ 46.5 billion . Similarly, hybrid cloud infrastructures (use of private and public clouds simultaneously) are more and more numerous.
The future of hybrid cloud security
In 2017, the deployment of the public cloud grew the fastest (+ 26%). While traditional infrastructure spending was still in the majority, it was plummeting in 2016 (-62%).
For 2018, the technological trend will remain with the Cloud, which will become more and more a vector of competitive differentiation “thanks to the value creation capabilities that APIs allow” according to Diego Segre, vice president and business partner of IBM Europe. The IDC forecasts a further increase in spending of more than 23% by 2018. According to the same study, investments in the cloud and especially in the public cloud will continue to increase by 2021 to reach more than 277 billion dollars in the USA.
According to Gartner , in 2018, 60% of companies that have implemented visibility and control tools for their cloud will experience one-third fewer security breaches. And until 2020, workloads on public clouds are expected to experience 60 percent fewer security incidents than those hosted in traditional data centers.

But if the cloud tends to be democratized, the security of it remains the main concern for businesses. Yet some simple elements are to be taken into account. We deliver below 7 tips to get you started and secure your hybrid infrastructure:
Tip # 1: Plan your deployment
Time is money. This is also the main problem of the hybrid cloud for businesses. Indeed, they want to migrate to a new infrastructure as quickly as possible to be operational and take advantage of the power of the cloud. However, setting up such an infrastructure takes time and wanting to go too fast, its security is endangered.
In order to properly organize its hybrid infrastructure, the company must view it as a new project in order to devote the necessary time and resources. It is imperative to build on good foundations to avoid a complete resumption of a strategy that will have a direct impact on the business activity. Without this, the company could suffer financially from subsequent computer attacks. And when we know that on average, in 2017, cyberattacks cost $ 7.9 million to French companies, it is better to make arrangements upstream.
Tip # 2: Restrict Access
Companies make the mistake of believing that everything on their network or the cloud is protected. However, without security tools (such as Elastic Workload Protector for example), it is not the case. All data can be exposed on the Internet. To avoid this, you have to apply zero trust. This approach must be implemented in all environments and applications of the company. The latter must first check the communications between its networks, infrastructures and applications.
Separation of access is also required, for example by level of responsibility (giving certain access privileges to administrators). It is a good idea to give administrators or users access only to the environments they need (development and pre-production environments and limit production access for developers). Cloud providers (such as Azure or AWS ) provide these access managements.
