The goal of transcending flesh is an old fetish. Yogis meditated and fasted for eons in order to rise above our meat casing, performing painful ablutions and inventing kriyas, intense breathing exercises that are physiologically indistinct from intentional hyperventilation. The goal of many religions, from some forms of Tibetan Buddhism to numerous strains of Christianity and Islam, is all about letting the spirit soar free.

While language changes, pretensions remain. Today we talk about uploading consciousness to an as of yet discovered virtual cloud. Artificial intelligence is only moments away, so the story goes, with experts weighing in on the ethical consequences of creating machines void of emotional response systems. In this view consciousness, itself a loaded and mismanaged term, is nothing more than an algorithm waiting to be deciphered. Upon cracking the code, immortality awaits.

Of course others are more grounded. The goal of extending life to 150 years includes the body by default, though the mind is still championed above all else. Yet we seem to age in opposing directions by design. At forty-one little has changed in how I think about myself, yet my body is decaying: a post-knee surgery creek here, a perpetual tight shoulder there. It certainly feels like a slowly approaching transition, even if that, like much of life, is an illusion.

The brain has rightfully been placed as the seat of consciousness. It is certainly the weigh station where all perceptions pass through. Yet in discussion of becoming robots an essential facet of life is missed: consciousness is not only produced by your brain, it is also your nervous systems response to the environment. In this sense it might be better to think of your entire body as your brain.

Thats an argument cognitive scientist Guy Claxton is making. History might belong to Hippocratic holism and Cartesian dualism, but in the past few decades scientists have become serious neurological fanboys. Breakthrough technologies made non-invasive means of measuring blood flow available, reshaping how we think about metacognition. No longer do we only know that we think, we can now witness how our brain responds to every single thought and emotion, then string together the threads in the fabric of cognition.

When we believe a separate mind (or spirit) exists apart from our body, Claxton writes, we make worse decisions regarding our body. He points to a study at the University of Cologne in which two groups read texts, one in support of dualism, the other expressing mind and body as part of the same being.

Not only did the dualists report less engagement and interest in healthy behaviours and attitudes than the physicalists, they were actually more likely to choose the chips than the salad when they went off for lunch.

Which is effectively how we always act. Dualism supports everything from suicidal terrorism to environmental destructionif you believe another spirit world better than this one awaits, why care about what we do to the planet and its resources? We were put here to lord over this domain anyway.

Historian Yuval Noah Harari finds this phenomenon apparent in everything from religion to economics. In Homo Deus, he argues that as we transformed from animals struggling to survive to animals that thrive our main pursuit became pleasure. Impatient creatures we are, we swerve manically between stress and boredom in the perpetual quest for gratification, taking out whatever stands in our way.

Case in point: Today the headlines proclaim that the Dow Jones passed 21,000 for the first time in history. Immediately speculators started wondering what does 30,000 look like? The myth of perpetual progress creates an impossible load for the planet to handle. Harari believes the incessant anxiety of unfettered growth is digging us a certain grave. Because we train our eyes on the markets algorithms, however, were blinded to the destruction our surroundings. Then someone says that climate change is merely an engineering problem and we think, Sure, why not? Just more numbers on a screen to be managed.

This disembodiment from our environment comes with a heavy toll. Harari cites the Buddha, who taught that the pursuit of pleasure is the root of suffering. Upon achieving a goal we dont pause to revel in satisfaction. Instead we immediately crave more, dopamine monkeys chasing grapes.

Claxton finds a partial solution in yoga and meditation, which help in the development of embodied cognition. (Harari meditates two hours every day, and performs one sixty-day Vipassana retreat each year.) The relationship between our body and mind is critical for self-understanding. That we ever separated them is likely an aberration of biological development, as Paul Bloom points out. Cognitive software updates might be constant, but upgrading physiological hardware takes quite some time, and so the feeling of dualism is likely to persist.

Matthew Crawford believes the disembodied culture fostered since the Industrial Revolution diminishes personal autonomy. He left a lucrative career at a D.C. think tank to work as a motorcycle mechanic, resulting in one of the best books on this subject Ive read. He finds manual work more intellectually engaging than sitting behind a computer selling political agendas. The fact that education is mostly focused on technology is unfortunate, as it promotes disassociation from the world we live in.

The disappearance of tools from our common education is the first step toward a wider ignorance of the world of artifacts we inhabit.

Weve made some strides of late, however, at least with our own bodies if not tools. While physicality has generally been removed from our daily workload, the exercise industry continues to expand. Six days a week I move bodies in yoga and fitness classes. People inherently recognize theyre not only toning and stretching their muscles and fascia. Emotional catharsis and mental focus keeps studios and gyms crowded. If emotional intelligence has been a catchphrase over the last decade, a renaissance in physical intelligence is occurring.

Thats important. Rewarding careers that push numbers from bank account to bank account instead of those responsible for building the buildings those computers sit inside is an indication of how disembodied weve become as a culture. Championing sedentary behavior in the quest of prosperous algorithms is a modern tragedy we dont pay enough attention to. More than our personal well-being is at stake. We need our bodies as much as our brains, a lesson we need to learn before atrophy is complete.

If you have a new app or use case requiring scalable, on-demand or pay-as-you-go storage, one or more public cloud storage services will probably make your short list. It's likely your development team has at least dabbled with cloud storage, and you may be using cloud storage today to support secondary uses such as backup, archiving or analytics.

Every cloud storage option has its pros and cons. Depending on your specific needs, the size of your environment, and your budget, its essential to weigh all cloud and on-prem options. Download this comprehensive guide in which experts analyze and evaluate each cloud storage option available today so you can decide which cloud model public, private, or hybrid is right for you.

While cloud storage has come a long way, its use for production apps remains relatively limited. Taneja Group surveyed enterprises and midsize businesses in 2014 and again in 2016, asking whether they are running any business-critical workloads (e.g., ERP, customer relationship management [CRM] or other line-of-business apps) in a public cloud (see "Deployments on the rise"). Less than half were running one or more critical apps in the cloud in 2014, and that percentage grew to just over 60% in 2016. Though cloud adoption for critical apps has increased significantly, many IT managers remain hesitant about committing production apps and data to public cloud storage providers.

Concerns about security and compliance are big obstacles to public cloud storage adoption, as IT managers balk at having critical data move and reside outside data center walls. Poor application performance, often stemming from unpredictable spikes in network latency, is another top-of-mind issue. And then there's the cost and difficulty of moving large volumes of data in and out of the cloud or within the cloud itself, say when pursuing a multicloud approach or switching providers. Another challenge is the need to reliably and efficiently back up cloud-based data, traditionally not well supported by most public cloud storage providers.

How can you overcome these kinds of issues and ensure your public cloud storage deployment will be successful, including for production workloads? We suggest using a three-step process to assess, compare and contrast providers' key capabilities, service-level agreements (SLAs) and track records so you can make a better informed decision (see: "Three-step approach to cloud storage adoption").

Let's examine specific security, compliance and performance capabilities as well as SLA commitments you should look for when evaluating public cloud storage providers.

Maintaining cloud data storage security is generally understood to operate under a shared responsibility model: The provider is responsible for security of the underlying infrastructure, and you are responsible for data placed on the cloud as well as devices or data you connect to the cloud.

All three major cloud storage infrastructure-as-a-service providers (Amazon Web Services [AWS], Microsoft Azure and Google Cloud) have made significant investments to protect their physical data center facilities and cloud infrastructure, placing a particular emphasis on securing their networks from attacks, intrusions and the like. Smaller and regional players tend also to focus on securing their cloud infrastructure. Still, take the time to review technical white papers and best practices to fully understand available security provisions.

Though you will be responsible for securing the data you connect or move to the cloud, public cloud storage providers offer tools and capabilities to assist. These generally fall into one of three categories of protection: data access, data in transit or data at rest.

Data access: Overall, providers allow you to protect and control access to user accounts, compute instances, APIs and data, just as you would in your own data center. This is accomplished through authentication credentials such as passwords, cryptographic keys, certificates or digital signatures. Specific data access capabilities and policies let you restrict and regulate access to particular storage buckets, objects or files. For example, within Amazon Simple Storage Service (S3), you can use Access Control Lists (ACLs) to grant groups of AWS users read or write access to specific buckets or objects and employ Bucket Policies to enable or disable permissions across some or all of the objects in a given bucket. Check each provider's credentials and policies to verify they satisfy your internal requirements. Though most make multifactor authentication optional, we recommend enabling it for account logins.

Data in transit:To protect data in transit, public cloud storage providers offer one or more forms of transport-level or client-side encryption. For example, Microsoft recommends using HTTPS to ensure secure transmission of data over the public internet to and from Azure Storage, and offers client-side encryption to encrypt data before it's transferred to Azure Storage. Similarly, Amazon provides SSL-encrypted endpoints to enable secure uploading and downloading of data between S3 and client endpoints, whether they reside within or outside of AWS. Verify that the encryption approach in each provider's service is rigorous enough to comply with relevant security or industry-level standards.

Data at rest:To secure data at rest, some public cloud storage providers automatically encrypt data when it's stored, while others offer a choice of having them encrypt the data or doing it yourself. Google Cloud Platform services, for instance, always encrypt customer content stored at rest. Google encrypts new data stored in persistent disks using the 256-bit Advanced Encryption Standard (AES-256) and offers you the choice of having Google supply and manage the encryption keys or doing it yourself. Microsoft Azure, on the other hand, enables you to encrypt data using client-side encryption (protecting it both in transit and at rest) or to rely on Storage Service Encryption (SSE) to automatically encrypt data as it is written to Azure Storage. Amazon's offering for encrypting data at rest in S3 is nearly identical to Microsoft Azure's.

Also, check for data access logging -- to enable a record of access requests to specific buckets or objects -- and data disposal (wiping) provisions, to ensure data's fully destroyed if you decide to move it to a new provider's service.

Your provider should offer resources and controls that allow you to comply with key security standards and industry regulations. For example, depending on your industry, business focus and IT requirements, you may look for help in complying with Health Insurance Portability and Accountability Act, Service Organization Controls 1 financial reporting, Payment Card Industry Data Security Standard or FedRAMP security controls for information stored and processed in the cloud. So be sure to check out the list of supported compliance standards, including third-party certifications and accreditations.

Unlike security and compliance, for which you can make an objective assessment, application performance is highly dependent on IT environment, including cloud infrastructure configuration, network connection speeds and the additional traffic running over that connection. If you're achieving an I/O latency of 5 to 10 milliseconds running with traditional storage on premises, or even better than that with flash storage, you will want to prequalify application performance before committing to a cloud provider. It's difficult to anticipate how well a latency-sensitive application will perform in a public cloud environment without actually testing it under the kinds of conditions you expect to see in production.

Speed of access is based, in part, on data location, meaning expect better performance if you colocate apps in the cloud. If you're planning to store primary data in the cloud but keep production workloads running on premises, evaluate the use of an on-premises cloud storage gateway -- such as Azure StorSimple or AWS Storage Gateway -- to cache frequently accessed data locally and (likely) compress or deduplicate it before it's sent to the cloud.

To further address the performance needs of I/O-intensive use cases and applications, major public cloud storage providers offer premium storage capabilities, along with instances that are optimized for such workloads. For example, Microsoft Azure offers Premium Storage, allowing virtual machine disks to store data on SSDs. This helps solve the latency issue by enabling I/O-hungry enterprise workloads such as CRM, messaging and other database apps to be moved to the cloud. As you might expect, these premium storage services come with a higher price tag than conventional cloud storage.

Bottom line on application performance: Try before you buy.

A cloud storage service-level agreement spells out guarantees for minimum uptime during monthly billing periods, along with the recourse you're entitled to if those commitments aren't met. Contrary to many customers' wishes, SLAs do not include objectives or commitments for other important aspects of the storage service, such as maximum latency, minimum I/O performance or worst-case data durability.

In the case of the "big three" providers' services, the monthly uptime percentage is calculated by subtracting from 100% the average percentage of service requests not fulfilled due to "errors," with the percentages calculated every five minutes (or one hour in the case of Microsoft Azure Storage) and averaged over the course of the month.

Typically, when the uptime percentage for a provider's single-region, standard storage service falls below 99.9% during the month, you will be entitled to a service credit. (Though it's not calculated this way for SLA purposes, 99.9% availability implies no more than 43 minutes of downtime in a 30-day month.) The provider will typically credit 10% of the current monthly charges for uptime levels between 99% and 99.9%, and 25% for uptime levels below 99% (Google Cloud Storage credits up to 50% if uptime falls below 95%). Microsoft Azure Storage considers storage transactions failures if they exceed a maximum processing time (based on request type), while Amazon S3 and Google Cloud Storage rely on internally generated error codes to measure failed storage requests. Note that the burden is on you as the customer to request a service credit in a timely manner if a monthly uptime guarantee isn't met.

Also, carefully evaluate the SLAs to determine whether they satisfy your availability requirements for both data and workloads. If a single-region service isn't likely to meet your needs, it may make sense to pay the premium for a multi-region service, in which copies of data are dispersed across multiple geographies. This approach increases data availability, but it won't protect you from instances of data corruption or accidental deletions, which are simply propagated across regions as data is replicated.

With these guidelines and caveats in mind, you can better assess whether public cloud storage makes sense for your particular use cases, data and applications. If public cloud storage providers' service-level commitments and capabilities fall short of meeting your requirements, consider developing a private cloud or taking advantage of managed cloud services.

Though public cloud storage may not be an ideal fit for your production data and workloads, you may find it fits the bill for some of your less demanding use cases.
