• Comprehend your workloads prior to transitioning to the cloud.
• Be mindful of the expenses related to cloud services.
• Equip your team with the essential understanding for cloud governance.
• Select a trustworthy partner for evaluating and overseeing the migration.
• Use infrastructure-as-code for effective administration and security.

There are numerous reasons to move to the cloud, but the method an organization selects to make the transition can greatly impact the outcomes it experiences upon arrival.

Important Factors to Consider for Cloud Migration

According to Kris Jackson, the general manager of cloud infrastructure and security at Fusion5, advantages like lowered expenses, enhanced security, and better governance can be realized, though they are contingent on how well the migration is strategized and performed.

Understanding Workloads

“Firstly, ensure you have a thorough understanding of the workloads in your environment,” Jackson advises. This includes recognizing which applications and data require migration and comprehending their dependencies and performance needs.

Cost Awareness

The second important point is to ensure you understand that every minute a service operates in the cloud incurs charges. Cloud services use a pay-as-you-go model, so inefficiencies can swiftly result in excessive costs if not properly managed.

Team Preparedness

Furthermore, consider whether your business is truly prepared to handle workloads in the cloud. Does your team possess adequate knowledge of cloud concepts and the necessary governance and control measures? It is essential to provide proper training and preparation to your team to avoid mismanagement and ensure smooth operations after migration.

The Significance of a Trustworthy Companion

Jackson underscores the significance of selecting a partner capable of both accurately evaluating and overseeing the migration process, as well as training internal resources. This guarantees that the staff can effectively handle the new environment.

Infrastructure-as-Code

This opens up the possibility to shift from utilizing traditional processes for cloud management to employing machine-readable definition files, a strategy known as infrastructure-as-code. According to Jackson, this method can result in further cost savings through automation of management tasks and enhanced security.

“It’s crucial to comprehend how your team will function in the new setting and which tools they will utilize to take advantage of that automation,” Jackson explains.

Summary

Migrating to the cloud presents various advantages such as lowering expenses, boosting security, and strengthening governance. Nevertheless, comprehending workloads, being mindful of costs, and readying your team are crucial steps for a smooth transition. Collaborating with professionals such as Fusion5 can facilitate the process and secure lasting success by implementing strategies like infrastructure-as-code.

Fusion5 can assist by evaluating and overseeing the migration process, training internal teams, and offering expertise in utilizing infrastructure-as-code for effective management and improved security.

What Happened?

CrowdStrike, a prominent American cybersecurity company recognized for its endpoint security solutions, released an update that unintentionally led to a worldwide IT outage. This flaw resulted in the notorious Blue Screen of Death (BSOD) on Windows computers, causing continuous reboot loops and considerable disturbances.

The problem started at approximately 4 PM Australian time on Friday, July 19, 2024. Initially blamed on Microsoft, further investigation identified CrowdStrike’s update as the cause. This unprecedented incident had far-reaching consequences:

• Turmoil in travel: A multitude of flights were either cancelled or delayed globally.
• Operational disruptions were experienced by banks, hospitals, emergency services, and media organizations.
• Economic consequences: Companies suffered financial losses due to mandatory closures or decreased productivity.
• Significant disruption: Crucial services such as online banking and hospital systems experienced interruptions.

Root Cause Analysis

CrowdStrike’s update tried to access an invalid memory address (0x9c), causing Windows to instantly shut down the application. This invalid access occurred because of a NULL pointer in the memory-unsafe C++ language. Given that security software has extensive access to system files, this error resulted in widespread system crashes.

Resolution Steps

To address the problem, CrowdStrike released a public announcement and detailed the procedures for impacted firms.

1. Starting Windows in Safe Mode can be difficult for devices deployed in an enterprise environment because of Bitlocker encryption.
2. Delete the problematic update—it’s more straightforward once you enter Safe Mode.

CrowdStrike stopped the spread of the flawed update and focused on releasing a fixed version. However, addressing the issue was intricate and lengthy, necessitating physical access to numerous devices.

Future Prevention Strategies

The incident highlights the necessity for stringent testing procedures and gradual implementations for crucial updates. It is imperative for security vendors to ensure their code undergoes extensive automated and manual testing prior to deployment. Gradual rollouts, akin to Microsoft’s Windows Insider Release Rings, could assist in reducing such risks by identifying problems at an early stage with smaller groups.

Moreover, operating systems such as Windows ought to integrate features that enable the rollback of faulty drivers without necessitating a full reboot or considerable manual effort.

CyberCX notified their customers about the outage impacting Australian and New Zealand organizations, while Tesserent confirmed that devices running Microsoft Windows in conjunction with CrowdStrike were encountering ‘blue screen’ errors and repeated reboot attempts.

CrowdStrike’s Response

CrowdStrike does not offer a publicly available service status page. An apparently leaked image from its secured forums indicated a connection between ‘Windows crashes and the Falcon sensor’. As stated in the technical documentation, the Falcon sensor is a minimal, endpoint-installed agent designed to scrutinize network connections for indications of harmful activity.

Widespread Global Impact

Various organizations continue to be affected, including businesses, supermarkets, fast-food chains, certain airlines, and services at major airport terminals. Telstra also announced it was impacted by a global issue involving both Microsoft and CrowdStrike. Rail freight company Aurizon confirmed that its operations were disrupted due to these outages, impacting several train services across its network.

Banks, payment services, and governmental entities were also reported to be encountering problems. Similar disruptions were seen in other global markets, including the US and Europe. The US Federal Aviation Administration (FAA) went so far as to issue a ground stop for flights because of an ‘airline IT issue’.

Government Response

The Australian government is actively participating in managing the response to this incident. Australia’s Home Affairs Minister Clare O’Neil mentioned that CrowdStrike joined a national coordination mechanism meeting organized by the government because of the incident’s increasing severity. The government is concentrating on unifying the affected parties and ensuring that governmental bodies promptly implement the solution.
